[Psychotropic drug use and mental psychiatric disorders in France; results of the general population ESEMeD/MHEDEA 2000 epidemiological study].

INTRODUCTION: The use of psychotropic drugs is high in France and has increased over the last two decades. To date, no national study evaluating psychotropic drug use in the context of the diagnosis of psychiatric disorders has been performed. Such data has now been generated in the ESEMeD/MHEDEA 2000 study, which has allowed comparison of the situation in France with that in five other European countries (Germany, Belgium, Spain, the Netherlands and Italy). OBJECTIVES: 1) To describe the declared use of psychotropic drugs (globally and by therapeutic class) in order to evaluate annual prevalence, treatment duration and demographic factors associated with use. 2) To estimate the proportion of subjects with an anxiety disorder, mood disorder or alcohol-related disorder (abuse or dependence) that have been appropriately treated with an antidepressant or anxiolytic drug. 3) to evaluate the proportion of psychotropic drug users who fulfil diagnostic criteria for these three classes of psychiatric disorder. METHODS: This was a transversal survey carried out between 2001 and 2003 of non-institutionalised subjects aged 18 or over in the general population of Germany (n = 3,555), Belgium (n = 2,419), Spain (n = 5,473), France (n = 2,894), the Netherlands (n = 2,372) and Italy (n = 4,712). In France, the sampling source used was a randomly generated list of telephone numbers. Subjects were interviewed at home by professional interviewers. The WMH-CIDI questionnaire was used. RESULTS: In France, 21% of subjects interviewed (n = 580) had taken at least one psychotropic drug during the year. For 19%, this was an anxiolytic or hypnotic (AX-HY), for 6.0% an antidepressant (AD), for 0.8% an antipsychotic (AP) and for 0.4% a mood regulating drug (TY). The distribution of users of AX-HY according to treatment duration was the following: 44% (1 to 15 days), 13% (16 to 30 days), 14% (1 to 3 months), 6.7% (3 to 6 months) and 23% (> 6 months). For users of ADs, the distribution was: 21% (1 to 15 days), 7.8% (16 to 30 days), 18% (1 to 3 months), 12% (3 to 6 months) and 42% (> 6 months). For subjects fulfilling diagnostic criteria for a mood disorder in the previous year or over their lifetime, 43% and 29% respectively had taken an AX-HY in the last twelve months and 29% and 16% an AD. For those who fulfilled diagnostic criteria for an anxiety disorder in the previous year or over their lifetime, the use of an AX-HY, in the last twelve months, concerned 43% and 30% of subjects respectively, whilst that of AD concerned 16% and 14%. For previous year or lifetime alcohol-related disorders, AX-HY use, in the last twelve months, concerned 63% and 22% of subjects respectively and use of ADs 9.3% and 7.2%. Amongst users of AX-HY in the last twelve months, a previous year or lifetime diagnosis of mood disorders was made for 16% and 39% of subjects respectively. Amongst users of ADs, the respective prevalence was 31% and 64%. A twelve-month and lifetime diagnosis of anxiety disorders was identified in 22% and 37% of users of AX-HY and among 27% and 50% of users of AD respectively. A twelve-month and lifetime diagnosis of alcohol-related disorders was found in 2.5% and 6.6% of users of AX-HY and among 1.1% and 7.8% of users of AD respectively. 68% of users of AX-HY had fulfilled none of these diagnostic criteria in the previous 12 months and 46% had never fulfilled them in their lifetime. With respect to AD users, the proportion who did not meet these diagnostic criteria in the previous 12 months was 56%, compared to 20% over their lifetime. Comparison of the French data from the study with those of the entire European sample showed that the annual prevalence of AX-HY and AD use was higher in France with mean treatment durations that were shorter. For antipsychotics and mood regulators, no clear differences were observed between France and the six countries of the study taken together. DISCUSSION: Over the last two decades, use of AX-HY seems to have decreased in France, even though it remains higher than that observed in the other European countries participating in this study. This high use can be explained in part by the observation that, in around half the cases, it corresponds to occasional use. In contrast, the use of antidepressants has increased. In subjects with recent mood disorders or anxiety disorders, the use of AX-HY remains higher than that of antidepressants. Finally among users of AX-HY, only half of them had presented a mood disorder, anxiety disorder or alcohol use disorder during their lifetime, whereas this proportion rose to 80% for users of antidepressants.

Controlled trial of faecal occult blood testing in the detection of colorectal cancer.

20 525 patients from general practitioners' lists were randomly allocated into test and control groups. The 10 253 test subjects were invited to perform haemoccult faecal occult blood testing over 3 days. 3613 (36 . 8%) of the 9807 who received their invitations completed the test. Compliance was improved by direct invitation from the general practitioner and by prior health education by letter or interview. 77 people (2 . 1%) had a positive test result, and 50% of these on investigation had neoplastic disease--12 had invasive carcinomas (9 Dukes' stage A, 2 stage B, 1 stage C) and 27 had 40 adenomas (12 over 2 cm, 2 of which contained areas of severe dysplasia). In the year following the screening test 1 carcinoma (stage C) has presented in the group which accepted the test, and 10 carcinomas (4 stage B, 4 stage C, 2 stage D) have presented in the control group. This respresents a 3 . 6 times greater detection rate per 1000 persons in the test group than in the control group. Only 8 adenomas have presented in the control and non-responding groups. Fibreoptic sigmoidoscopy identified the 10 carcinomas within its range and 39 of the 40 adenomas. Double-contrast barium enema identified only 9 of the 12 carcinomas and 24 (62%) of the 40 adenomas. All 3 carcinomas not identified by barium enema were polypoid Dukes' stage-A lesions.

Outpatient wound preparation and care: a national survey.

STUDY OBJECTIVE: To sample the practice styles of emergency physicians caring for acute traumatic wounds. DESIGN: Written survey. SETTING: US emergency departments obtained from the American College of Emergency Physicians mailing list. SUBJECTS: Randomly selected ACEP members. MAIN RESULTS: One hundred fifty-one of 285 (53%) survey mailings were returned. Eighty-six percent of respondents were primarily clinicians, and the majority (61.6%) worked in EDs with annual patient visits between 21,000 and 50,000. The majority of respondents (64.2%) were certified by the American Board of Emergency Medicine. Nineteen percent managed wounds based on provider preference despite the existence of written wound management protocols. We identified a variety of practices that are contrary to current literature and textbook recommendations. Fifty-eight (38%) soaked wounds, whereas 21% used either 10% povidone iodine or hydrogen peroxide to cleanse wounds. One hundred one (67%) scrubbed the entire wound surface using, among other methods, cotton gauze (59%) or a coarse, bristle-laden sponge (38%). Forty (27%) irrigated wounds using techniques that have not been proven to deliver the 5 to 8 psi necessary for adequate tissue cleansing. Delayed primary closure, a treatment option for lacerations at increased risk for infection, was infrequently or never practiced by 76% of respondents. All respondents administered IV antimicrobials at least occasionally for simple outpatient lacerations. CONCLUSION: Methods of preparing, treating, and following outpatient wounds vary among emergency physicians, and these results support the idea that no de facto standard of care exists for this clinical problem. Outpatient wound care techniques routinely practiced (ie, soaking, scrubbing, use of full-strength hydrogen peroxide or full-strength povidone iodine) may be harmful based on limited animal and human research, whereas other proven techniques (ie, delayed primary closure) are infrequently practiced by many emergency physicians.

Dietary and behavioral risk factors for urolithiasis: potential implications for prevention.

Few studies have examined urolithiasis in primary care populations, and limited data are available on non-drug interventions to reduce the risk for urinary calculi. Therefore, we conducted a case control study of patients enrolled in a large prepaid health maintenance organization. The 240 study cases were men experiencing initial episodes of urolithiasis, ascertained by reviewing radiology procedure logs and medical records. The 392 controls were age-matched men with no history of urolithiasis chosen from a list of randomly selected men. Data were collected using standardized telephone interviews. Odds ratios were calculated for potential risk factors. In logistic regression analyses the risk for urinary tract calculi was related to both consumption variables, such as a low-fat or weight reduction diet (adjusted odds ratio, 0.41; P < 0.0005) and beer drinking (adjusted odds ratio, 0.41; P < 0.0001), and to demographic variables, such as African-American ethnicity (adjusted odds ratio, 0.29; P = 0.03) and a positive family history (adjusted odds ratio, 2.22; P < 0.001). These findings suggest the need to evaluate appropriate behavioral interventions to reduce the morbidity associated with urolithiasis. Prospective studies should evaluate the possibilities that beer drinking, even in modest amounts, and a low-fat or weight reduction diet are associated with substantial reductions in risk.

Secondhand effects of student alcohol use reported by neighbors of colleges: the role of alcohol outlets.

This is a study of the secondhand effects of student alcohol use experienced by residents of neighborhoods near college campuses. We examined the relationship of a college's level of binge drinking and the number of alcohol outlets in the immediate area, to lowered quality of neighborhood life through such secondhand effects. Adults from 4661 households in the United States were interviewed through a stratified list-assisted random digit dialing telephone survey. The interview schedule included questions about residents' experiences of secondhand effects of alcohol use such as noise, vandalism or public disturbances. Reports about the quality of neighborhood life provided by respondents residing near colleges were compared with those of respondents who did not live near colleges; and reports of neighbors of colleges with high rates of binge drinking were compared with those of neighbors of colleges with lower rates. The presence of alcohol outlets in these areas was also compared. Residents near colleges and particularly near colleges with heavy episodic drinking reported the presence of more alcohol outlets within a mile. Those neighborhoods were characterized by lower socioeconomic status. Neighbors living near college campuses were more likely to report a lowered quality of neighborhood life through such secondhand effects of heavy alcohol use as noise and disturbances, vandalism, drunkenness, vomiting and urination. A path analysis indicated that the number of nearby alcohol outlets was an important factor mediating the relationship between colleges, especially those with high rates of binge drinking, and such secondhand effects. The results suggest that neighborhood disruptions around colleges due to heavy alcohol use may be reduced by limiting the presence of alcohol outlets in those areas, and the marketing practices that this engenders.

Associative List Memory.

This paper introduces an Associative List Memory (ALM) that has high recall fidelity with low memory and low processing requirements. This permits a simple implementation in software on a personal computer or space instrument microprocessor. Associative List Memory has a performance comparable with Sparse Distributed Memory (SDM) but differs from SDM in that convergence occurs during learning, rather than on recall, and in that the memory is in the form of a dynamic list rather than static randomly distributed locations. Associative List Memory is suitable for unsupervised finding of classes of phenomena in large databases. In particular, all of the class exemplars deduced can be easily accessed at any time to provide a summary of current database knowledge, being essentially the contents of the list. Examples are given where patterns of 1000 bits length with > 30% noise can be learned unsupervised to deduce the original pattern's noise free. A second pass through the data in recall mode can be used to assign to each input the appropriate original pattern, effectively removing all noise from the input data. At large input bit sizes the recall fidelity approaches closely to the maximum possible value. Associative List Memory compares well in recall fidelity with SDM and other associative memories. Its processing times on a personal computer are found to be practical for database applications. Implemented within a space instrument processor, ALM would greatly reduce downlink data transmission rates. Copyright 1997 Elsevier Science Ltd.

A population-based case-control study of carotenoid and vitamin A intake and ovarian cancer (United States).

OBJECTIVE: To evaluate the association between dietary intake of carotenoids and vitamin A and the incidence of ovarian cancer. METHODS: We conducted a population-based case-control study of ovarian cancer in Massachusetts and Wisconsin. Incident cases diagnosed between 1991 and 1994 were identified through statewide tumor registries. We selected community controls at random from lists of licensed drivers and Medicare recipients; 327 cases and 3129 controls were included in the analysis. Data were collected by telephone interview, which included an abbreviated food and supplement list to quantify typical consumption of carotenoids (lutein/zeaxanthin, alpha-carotene, beta-carotene), retinol and total vitamin A at 5 years prior to diagnosis in cases, or to a comparable reference date in controls. Results were adjusted for age, state, and other risk factors. RESULTS: Participants with the highest dietary intake of lutein/zeaxanthin (> or =24,000 microg/week) experienced a 40% lower risk of ovarian cancer (95% CI = 0.36-0.99) compared to those with the lowest intake. Intake of alpha-carotene, beta-carotene, retinol and total vitamin A was unrelated to risk. Among foods, we observed non-significantly lower risks with high consumption of spinach, carrots, skim/lowfat milk and liver. CONCLUSION: These results support previous findings suggesting an inverse relationship between carotenoid intake and ovarian cancer risk.

Processing of formational, semantic, and iconic information in American sign language.

Three experiments examined short-term encoding processes of deaf signers for different aspects of signs from American Sign Language. Experiment 1 compared short-term memory for lists of formationally similar signs with memory for matched lists of random signs. Just as acoustic similarity of words interferes with short-term memory or word sequences, formational similarity of signs had a marked debilitating effect on the ordered recall of sequences of signs. Experiment 2 evaluated the effects of the semantic similarity of the signs on short-term memory: Semantic similarity had no significant effect on short-term ordered recall of sequences of signs. Experiment 3 studied the role that the iconic (representational) value of signs played in short-term memory. Iconicity also had no reliable effect on short-term recall. These results provide support for the position that deaf signers code signs from American Sign Language at one level in terms of linguistically significant formational parameters. The semantic and iconic information of signs, however, seems to have little effect on short-term memory.

The level-of-focal-attention hypothesis in oral reading: influence of strategies on the context specificity of lexical repetition effects.

Two experiments examined the influence of level of focal attention--text or lexical--on benefits from lexical repetition in speeded oral reading of coherent texts and random word lists. Experiment 1 showed that with coherent targets, direction of attention to the text level resulted in benefit only from a previous reading of the same coherent paragraph. However, when attention was directed to the lexical level, equal benefit resulted from a previous reading of either the same coherent paragraph or a scrambled version of the paragraph. Experiment 2 showed that level of focal attention did not influence benefit with scrambled targets. Thus, the linguistic structure of the target is important to repetition benefits and their modulation by attentional strategies.

Interresponse times in serial recall: effects of intraserial repetition.

The authors examined the effects of intraserial repetition on multitrial serial learning of random consonant lists, analyzing both learning rates and perfect trial interresponse times (IRTs). Lists varied along 3 dimensions: list length, presence or absence of a repeated element, and lag between repeated elements. After achieving a forward-recall criterion on a given list, participants (N = 20) attempted backward recall. At small lags, IRTs between the repeated elements were very short (compared with IRTs from identical positions in nonrepetition lists). At larger lags, the IRT to recall the second repeated item was substantially longer than in control lists. These results reveal a latency analogue of the Ranschburg pattern seen in accuracy data. A Ranschburg pattern was also found in participants' learning rates. These results both generalize the Ranschburg phenomenon and present further challenges to theories of serial order memory.

Use of an outcome by gestation table for extremely premature babies: a cross-sectional survey of the views of parents, neonatal nurses and perinatologists.

OBJECTIVES: To promote family-centered care and strengthen the process of informed consent it is essential that parents have access to information on the problems their baby may face. We have constructed an Outcome by Gestation Table (OGT) with information on survival, short-term complications plus treatments of the most recent cohort of babies born at different gestations from 23 to 28 weeks. This study documents the views on the table from parents of babies < 29 weeks gestation, neonatal nurses, and doctors. STUDY DESIGN: A copy of the OGT and a questionnaire seeking views regarding the OGT was sent to the parents' support group (Preemie-List), 71 randomly chosen perinatologists in Australia and to the 35 nurses working in our NICU. Differences between groups were analyzed using chi 2 analysis. RESULTS: Forty-eight parents participated in the study. Forty-three (60.5%) doctors and 24 (68.5%) neonatal nurses replied. The three groups agreed that the OGT is not misleading. The majority of doctors feel that the table: is easy to understand but has too much information; is useful but they are ambivalent about using it in their practice. The results were highly significant with parents being most positive and accepting of the OGT, next nurses and finally doctors. CONCLUSION: It is important to seek the views of both consumers and carers on any aid in communication in the NICU.

Sleep problems in primary school children: comparison between mainstream and special school children.

This paper reports on a study of the prevalence and social correlates of dyssomnias, features associated with obstructive sleep apnoea, and parasomnias in primary school children aged 4-12. Head teachers of schools selected randomly from lists of local primary and special schools were contacted by telephone and asked to distribute a questionnaire package to the parents of all pupils aged 4-12 years. In all, 890 parents of children from mainstream schools and 300 from special schools were approached. The response rates were 64.7% and 60%, respectively. The results showed that significantly higher proportions of children in special schools than in mainstream schools presented four of the five dyssomnias investigated and all of the features associated with obstructive sleep apnoea. In contrast, only two of the seven parasomnias were presented by higher proportions of the children in special schools. Age and gender differences for the two groups of children are presented. Finally, multiple correlations were computed between a range of child, family, and environmental characteristics and the three problems most frequently reported: frequency of settling problems; sleeping in the parents' bed; and night waking. The findings are discussed with reference to other studies of children's sleep problems, and the implications for treatment are considered.

Nurses' perceptions: issues that arise in caring for patients with diabetes.

Nurses' perceptions in caring for persons with diabetes have been little studied. To address this gap in the literature, a sample of nurses from a large Mid-western health care system were surveyed on nurses' perceptions of: (i) problems encountered in the care of patients with diabetes; (ii) problems encountered by patients and/or family member(s) in diabetes management; and (iii) nurses' suggested solutions. A randomly selected list of 200 registered nurses obtained from the health system's Department of Human Resources included inpatient, outpatient, emergency department, medical centre and home health care nurses. The sample was stratified to include 25% inpatient and 75% outpatient nurses. Of the 200 surveys mailed, 136 were returned (68% response rate). Twenty-four per cent of the 136 nurses reported they did not provide care for patients with diabetes. Of 103 nurses providing care to patients with diabetes, 98% were female, 91% were Caucasian, 76% were between the ages of 30 and 49 years, 57% worked in outpatient settings, 35% worked in primary care, and 42% had a bachelor's degree or higher. Of those with practice guidelines, 84% found the practice guidelines helpful. These nurses also perceived that they, as nurses, needed more education to improve their care of diabetes patients; few nurses believed it was within the scope of their practice to change treatment regimens. The perception of most nurse respondents was that acceptance of diabetes, knowledge deficits and non-compliance were primary patient problems in the management of diabetes. Nurses' perceptions of solutions to the problems centred on education of nurses and patients, and reinforcement of the importance of follow-up care.

Acceptability of solar disinfection of drinking water treatment in Kathmandu Valley, Nepal.

This research examines the acceptability of solar disinfection of drinking water (SODIS) in a village in Kathmandu Valley, Nepal, using constructs from the Health Belief Model as a framework to identify local understandings of water, sanitation and health issues. There has been no published research on the acceptability of SODIS in household testing in Nepal. Understanding the context of water and water purity in Nepalese villages is essential to identify culturally appropriate interventions to improve the quality of drinking water and health. Forty households from the village census list were randomly selected and the senior woman in each household was asked to participate. Baseline data on water sources and behaviors were collected in March 2002, followed by training in SODIS. Follow-up data were collected in June and July 2002. Only 9% of households routinely adopted SODIS. Participants mentioned the benefit of treating water to reduce stomach ailments, but this did not outweigh the perceived barriers of heavy domestic and agricultural workloads, other cultural barriers, uncertainty about the necessity of treating the water, and lack of knowledge that untreated drinking water causes diarrhea. Strategies for developing safe water systems must include public health education about waterborne diseases, source water protection, and a motivational component to achieve implementation and sustained use. In addition, other options for disinfecting water should be provided, given the women's work constraints and low level of formal education.

Household food insecurity is associated with adult health status.

The prevalence of household food security, which reflects adequacy and stability of the food supply, has been measured periodically in the United States and occasionally in high-risk groups or specific regions. Despite a plausible biological mechanism to suggest negative health outcomes of food insecurity, this relation has not been adequately evaluated. This study was conducted in the Lower Mississippi Delta region to examine the association between household food insecurity and self-reported health status in adults. A two-stage stratified cluster sample representative of the population in 36 counties in the Delta region of Arkansas, Louisiana, and Mississippi was selected using list-assisted random digit dialing telephone methodology. After households were selected and screened, a randomly selected adult was interviewed within each sampled household. Data were collected to measure food security status and self-reported mental, physical, and general health status, using the U.S. Food Security Survey Module and the Short Form 12-item Health Survey (SF-12). Data were reported on a sample of 1488 households. Adults in food-insecure households were significantly more likely to rate their health as poor/fair and scored significantly lower on the physical and mental health scales of the SF-12. In regression models controlling for income, gender, and ethnicity, the interaction between food insecurity status and race was a significant predictor of fair/poor health and lower scores on physical and mental health. Household food insecurity is associated with poorer self-reported health status of adults in this rural, high-risk sample in the Lower Mississippi Delta.

Association of soy and fiber consumption with the risk of endometrial cancer.

The authors conducted a case-control study among the multi-ethnic population of Hawaii to examine the role of dietary soy, fiber, and related foods and nutrients on the risk of endometrial cancer. Endometrial cancer cases (n = 332) diagnosed between 1985 and 1993 were identified from the five main ethnic groups in the state (Japanese, Caucasian, Native Hawaiian, Filipino, and Chinese) through the rapid-reporting system of the Hawaii Tumor Registry. Population controls (n = 511) were selected randomly from lists of female Oahu residents and matched to cases on age (+/-2.5 years) and ethnicity. All subjects were interviewed using a diet history questionnaire that included over 250 food items. Non-dietary risk factors for endometrial cancer included nulliparity, never using oral contraceptives, fertility drug use, use of unopposed estrogens, a history of diabetes mellitus or hypertension, and a high Quetelet's index (kg/cm2). Energy intake from fat, but not from other sources, was positively associated with the risk of endometrial cancer. The authors also found a positive, monotonic relation of fat intake with the odds ratios for endometrial cancer after adjustment for energy intake. The consumption of fiber, but not starch, was inversely related to risk after adjustment for energy intake and other confounders. Similar inverse gradients in the odds ratios were obtained for crude fiber, non-starch polysaccharide, and dietary fiber. Sources of fiber, including cereal and vegetable and fruit fiber, were associated with a 29-46% reduction in risk for women in the highest quartiles of consumption. Vitamin A and possibly vitamin C, but not vitamin E, were also inversely associated with endometrial cancer, although trends were not strong. High consumption of soy products and other legumes was associated with a decreased risk of endometrial cancer (p for trend = 0.01; odds ratio = 0.46, 95% confidence interval 0.26-0.83) for the highest compared with the lowest quartile of soy intake. Similar reductions in risk were found for increased consumption of other sources of phytoestrogens such as whole grains, vegetables, fruits, and seaweeds. Ethnic-specific analyses were generally consistent with these results. The observed dietary associations appeared to be largely independent of other risk factors, although the effects of soy and legumes on risk were limited to women who were never pregnant or who had never used unopposed estrogens. These data suggest that plant-based diets low in calories from fat, high in fiber, and rich in legumes (especially soybeans), whole grain foods, vegetables, and fruits reduce the risk of endometrial cancer. These dietary associations may explain in part the reduced rates of uterine cancer in Asian countries compared with those in the United States.

Reading habits of practicing physiatrists.

OBJECTIVE: Over the past 30 yr, the number of ACGME accredited specialties has quadrupled, and the number of journals cataloged on MEDLINE has doubled. Given this increase of information, this study sought to determine the amount and extent that pertinent journals are read by specialists in the field of physical medicine and rehabilitation. DESIGN: From a randomly selected list of board-eligible physiatrists and diplomates of the American Board of Physical Medicine and Rehabilitation, 1204 resident physicians, fellows, and attending physicians were sent questionnaires concerning their reading habits. The questionnaire contained a list of 36 journals adapted from a list of journals previously published as being pertinent to physical medicine and rehabilitation. Physicians were asked to specify which journals they read over the past year and how extensively these were read. Respondents were also asked to note whether they participated in an academic or private practice and if they read as much as they would like. RESULTS: The results revealed that very few journals were always read thoroughly, with the modal response among the more popular journals being that of "always scanned the table of contents and read the most important articles." Academic physiatrists were noted to read more than their private practice counterparts. Of the subspecialists who replied, 67% read a journal pertinent to their subspecialty. Eighty-three percent of all respondents reported that they did not read as much as they would like. CONCLUSION: Physiatrists are rarely able to completely read the most relevant journals in their field. When reading journals, most physiatrists only scan the table of contents and read the most important abstracts.

The role of context in reading with central field loss.

It has been suggested that readers with central field loss (CFL) may not be able to use context to facilitate reading in the same way that normally sighted readers do because their processing capacity is fully utilized decoding the degraded visual stimulus. If true, this could account for their slow reading, even when text is appropriately magnified. Readers with CFL and normally sighted, age-matched controls read sentences and lists of random words from two dynamic text displays. We used sentence-gain (the ratio of reading rates for sentences to random words) to assess the use of context. Sentence-gain was equivalent across groups. Therefore, reduced reliance on context cannot explain the slower reading rates of people with CFL.
