Understanding randomized controlled trial generalizability through an embedded molecular diagnostics trial.

BACKGROUND: Issues with randomized controlled trial generalizability are well described, but whether these issues result from differences in patient treatment across contexts remains unknown. We studied treatment of patients with high-risk prostate cancer after radical prostatectomy inside and outside a randomized controlled trial evaluating the impact of a genomic classifier on post-radical prostatectomy treatment decision making (Genomics in Michigan Impacting Observation of Radiation [G-MINOR]; ClinicalTrials.gov identifier NCT02783950). METHODS: G-MINOR enrolled 338 patients; propensity score-matched eligible but unenrolled patient cohorts (pretrial and trial contemporary) from the Michigan Urological Surgery Improvement Collaborative (MUSIC), in which the trial was embedded, were compared for rates and time to secondary treatment (adjuvant or salvage therapy) after prostatectomy. RESULTS: Among 338 patients in the G-MINOR cohort, 69 (31 adjuvant, 38 salvage) received secondary treatment compared with 266 (183 adjuvant, 83 salvage) and 104 (60 adjuvant, 44 salvage) in the 1014 contemporary and 338 pretrial-matched MUSIC cohorts. Time to secondary treatment was much shorter in the MUSIC cohort across all comparisons. For example, matching G-MINOR to synchronous MUSIC patients demonstrated 84% vs 74% estimated 2-year treatment-free survival for trial and real-world patients, respectively (P < .001). CONCLUSIONS: Controlling for key clinicopathologic factors, patients in the G-MINOR randomized controlled trial and MUSIC cohorts were treated differently, even after stratifying by genomic risk. These findings suggest that challenges in randomized controlled trial generalizability extend beyond the representativeness of trial participants. Differences in management may also explain why divergent patient outcomes are observed in randomized controlled trials vs real-world settings.

Endoscopic sclerosis and esophageal balloon tamponade in acute hemorrhage from esophagogastric varices: a prospective controlled randomized trial.

A prospective randomized controlled clinical trial was performed in 43 consecutive histologically proved cirrhotic patients with endoscopically proved actively bleeding esophageal varices. Twenty-two were randomly selected to have esophageal tamponade with the Sengstaken-Blakemore tube, and 21 were selected to have endoscopic sclerosis of the esophageal wall. The two groups were similar in demographic, clinical and laboratory data. Bleeding was controlled by the Sengstaken-Blakemore tube in 16 of 22 patients (73%) and by endoscopic sclerosis in 20 of 21 (95%). Among those controlled by the Sengstaken-Blakemore tube, seven (44%) rebled and three (43%) were again controlled by the Sengstaken-Blakemore tube; in the endoscopic sclerosis group, four (20%) rebled and three (75%) were controlled. Thus, hemorrhage was definitively controlled in 52% of patients and 66% of bleeding episodes in the Sengstaken-Blakemore tube group and in 90% of patients and 92% of bleeding episodes in the endoscopic sclerosis group. The definite control of hemorrhage was significantly better in the endoscopic sclerosis group (p less than 0.01). The Sengstaken-Blakemore tube patients received no definitive therapy after bleeding had been controlled. Within 30 days, six patients (27%) in the Sengstaken-Blakemore tube group had died compared to 2 (10%) in the endoscopic sclerosis group which is statistically significant (p less than 0.01) in favor of endoscopic sclerosis. The frequency of complications was similar in the two groups. Endoscopic sclerosis patients received serial endoscopic sclerosis after bleeding had been stopped during the whole period of follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical performance of monolithic and veneered zirconia three-unit posterior FDPs: A five-year multicenter randomized controlled trial.

AIM: This randomized controlled clinical study compared monolithic, partially veneered, and fully veneered zirconia FDPs over a 5-year period with respect to survival, technical and biological complications, and patient-reported outcome measures (PROMs). MATERIALS AND METHODS: Sixty-four patients requiring three-unit posterior FDPs were randomly allocated to monolithic (MONO-FDP), partially veneered (PV-FDP), or fully veneered (FV-FDP) groups. All FDPs were fabricated from 4 mol% Y₂O₃ partially stabilized zirconia (4Y-TZP). Follow-up examinations were conducted at baseline, 1, 3, and 5 years. Technical parameters were evaluated using modified USPHS criteria. Periodontal measurements (PPD, BOP, PI) and patient satisfaction were assessed at all time points. RESULTS: A total of 63 FDPs were evaluated at baseline, 57 at 3 years, and 54 at 5 years. Survival at 5 years was 94.7% for MONO-FDPs, 100% for FV-FDPs and 100% for PV-FDPs. Technical complications occurred exclusively in PV-FDP (33%) and FV-FDP (38%) groups and consisted of minor, polishable chipping; no chipping or fractures were recorded in MONO-FDPs (0%) with statistically significant difference between MONO-FDP and the other two groups (p ≤ 0.014). Biological parameters remained stable across all groups, with no significant differences in PPD, BOP, or PI. PV-FDPs and FV-FDPs tended to receive more favorable professional color ratings, whereas PROMs were similar among the groups. CONCLUSIONS: All three FDP designs-monolithic, partially veneered, and fully veneered-fabricated from 4Y-TZP zirconia demonstrated excellent 5-year clinical performance. Technical complications were limited to PV- and FV-FDPs and consisted of minor chipping. Biological outcomes and patient satisfaction were similar across groups. CLINICAL SIGNIFICANCE: The five-year outcomes suggest that veneered, partially veneered, and monolithic FDPs can be used with high clinical reliability; however, restorations incorporating veneering ceramic may present an elevated risk of ceramic chipping.

A randomized control trial of cardiac rehabilitation.

A randomized trial using controls tested whether psycho-social rehabilitation of acute myocardial infarction (MI) patients would improve significantly their return to work rate and assessed the importance of various psychological, social, occupational, socio-demographic, and medical factors in facilitating or impeding rapid return to work. Eighty-nine patients were assigned randomly to participate in an experimental cardiac rehabilitation program (rehab care), and 91 patients were controls who received conventional hospital rehabilitation (usual care). By the first follow-up interview at three months, patients assigned to experimental treatment were significantly less distressed psychologically and less dependent on family support than controls (P = 0.04 and P = 0.05, respectively). By the final follow-up interview at 13 months, there was a marginally significant difference in favor of the experimental group in the frequency of reported deterrents to work resumption (P = 0.07). However, the intervention did not result in a statistically significant difference in the return to work rate (P greater than 0.10). In each group, 88% were back at work by approximately the first year after infarction. In addition, the two groups were similar in the amount of time patients remained out of the workforce (median days rehab care = 75, usual care = 81; P greater than 0.10). A multi-stage data analysis procedure utilizing the Cox regression technique indicated that while several independent variables had significant univariate associations with the length of time patients convalesced, outcome was most influenced by the patient's initial cardiological status and clinical course, by the patterns of family support, and by the several variables measuring the presence of obstacles to resuming work. Our findings suggest that rehabilitation programs intervening on multiple levels (psychological, social, occupational, and physical) may best meet the needs of chronically ill cardiac patients. Results indicate that implementing measures addressing the patient's general psycho-social adjustment to MI may improve existing programs.

Effects of an internet-based combined exercise and cognitive-behavioral therapy intervention on endocannabinoid system biomarkers and physical fitness in adults with mild-to-moderate depression: a SONRIE randomized controlled trial.

BACKGROUND: This SONRIE randomized controlled trial (NCT05849792) examined the effects of a 12-week combined physical exercise and internet-based cognitive-behavioral therapy (iCBT) intervention on endocannabinoid system (ES) biomarkers and physical fitness in adults with mild-to-moderate depression. METHODS: Eighty adults were randomly assigned 1:1 to an intervention (IG) or control (CG) group. Outcomes included nine ES biomarkers (2-arachidonoylglycerol, 2-AG; anandamide, AEA; seven analogues) and physical fitness, including cardiorespiratory fitness (CRF; 6-minute walking test) and muscular strength. Measurements were taken at baseline, post-intervention and 8-week follow-up. Primary analysis performed 2 × 3 repeated-measures ANOVA on completers; mixed-effects intention-to-treat model as sensitivity analysis. RESULTS: No significant time × group interaction was detected for any ES biomarker, including 2-AG (F(2,88) = 0.17, p = 0.844) and AEA (F(2,88) = 1.20, p = 0.306); both groups showed comparable within-group decreases in 2-AG, 2-LG and 2-OG. The intervention significantly improved CRF [between-group difference + 81.6 m at 12 weeks (F(2,78) = 7.88, p = 0.001)], exceeding the established minimal clinically important difference. None of the exploratory muscular fitness outcomes reached statistical significance; the arm curl test showed a borderline non-significant interaction (F(2,78) = 2.83, p = 0.065). CONCLUSION: A 12-week internet-based combined exercise and iCBT intervention significantly improved CRF in adults with mild-to-moderate depression. We did not find evidence of an intervention-specific effect on plasma ES biomarkers. These findings support the inclusion of internet-delivered exercise and psychological interventions in comprehensive treatment strategies for depression. TRIAL REGISTRATION: ClinicalTrials.gov NCT05849792 (registered 6 May 2023).

Comparison of dietary protein with an oral, branched chain-enriched amino acid supplement in chronic portal-systemic encephalopathy: a randomized controlled trial.

A randomized study was conducted in 37 hospitalized patients at six cooperating hospitals in which protein-intolerant cirrhotic patients were fed increasing amounts of either dietary protein or a branched-chain enriched amino acid solution (BCAA) until they attained an intake of 80 gm protein per day or equivalent or until they developed stage 2 encephalopathy. All patients initially received 20 gm of dietary protein for 1 week, after which 20 gm of protein or BCAA were added weekly. Nitrogen balance improved from negative to positive in all patients in whom it was measured and increased equally in both groups. Seven of the 20 patients in the protein group and 1 of 17 in the BCAA group developed encephalopathy of stage 2 or greater (p less than 0.05). Changes in each component of the portal-systemic encephalopathy syndrome were compared, and differences were statistically significant for mental status grade (p less than 0.01), asterixis (p less than 0.05), Portal-systemic encephalopathy index (p less than 0.01), but insignificant for Number Connection Test, EEG or ammonia. Plasma amino acid profiles showed an increase in BCAA in the study group. Thus, oral BCAA supplements appear to induce positive nitrogen balance to approximately the same degree as an equivalent amount of dietary protein without inducing encephalopathy as frequently.

On randomized controlled trials and lifestyle interventions.

Randomized controlled trials (RCT) are viewed as the ultimate method for evaluation. The author claims that RCT do not enable full evaluation of lifestyle interventions in particular. Lifestyle interventions usually affect several diseases not measured by RCTs and the people who have undergone these interventions also have an impact on the lifestyle in their immediate environment. These potential biases indicate that RCTs underestimate the value of lifestyle interventions.

Effectiveness of Embedded Social Media Content on E-cigarette Attitudes and Behaviors: Results from a Randomized Control Trial.

BACKGROUND: This longitudinal randomized controlled trial examined the effects of anti-vaping social media content on e-cigarette attitudes and intentions among U.S. young adults (ages 18-24; n=3,400). METHODS: Targeted content was embedded directly into participants' social media feeds, with varying levels of impressions. RESULTS: Results indicate that increased exposure to anti-vaping messages significantly elevated perceived risk of harm (β=0.11, 95% CI: 0.03-0.20, p < .01) and social unacceptability of e-cigarette use (β=0.10, 95% CI: 0.03-0.18, p < .01), while decreasing intentions to vape (RRR = 0.59, 95% CI: 0.36-0.97, p < .05). Notably, these attitudinal shifts occurred even with relatively low ad exposure and over an extended intervention period, while controlling for the e-cigarette use status (never, former, or current) of participants. Discussion These findings support the effectiveness of digital media campaigns in influencing health-related behaviors and attitudes among young adults. Specifically, embedding anti e-cigarette content directly in the feed of young adults is shown to be effective in shifting attitudes in a space where these young adults are already engaged. Limitations include limited ad impressions and minimal change in ad awareness recall, suggesting future research should explore longer interventions and broader nicotine product messaging.

Nurse-Led Home-Based Mobile Health Cardiac Rehabilitation Program for Patients With Chronic Heart Failure: A Randomized Controlled Trial.

This 12-week randomized controlled trial evaluated a nurse-led mHealth intervention for patients with chronic heart failure, conceptually informed by Riegel's middle-range theory of self-care of chronic illness. The program integrated wearable activity tracking with weekly nurse-led behavioral coaching, reflecting the core self-care processes of monitoring, maintenance, and management. Compared with usual care, the intervention significantly improved daily step count, 6-minute walk distance, metabolic equivalents, and left ventricular ejection fraction. Findings highlight the effectiveness of theory-informed, nurse-delivered mHealth strategies in enhancing physical activity and cardiopulmonary function, while underscoring the critical role of advanced practice nurses in home-based chronic disease management.

Initial antihypertensive drug therapy: alpha blocker or diuretic. Interim report of a randomized, controlled trial.

A two-center, randomized, controlled trial designed to evaluate and compare an alpha blocker and a diuretic as initial antihypertensive drug treatment is currently in progress. Approximately 100 men and women, aged 30 to 69 years, are being randomly assigned to treatment with either of these two agents. If diastolic blood pressure is not reduced to its target level and is 85 mm Hg or higher, the alternate agent is added. The alternate agent is substituted if a patient does not tolerate the assigned agent. This preliminary report presents data concerning 62 patients who completed at least three of the planned 12 months of drug treatment. At that point, the alpha blocker prazosin and the diuretic hydrochlorothiazide were similar in their ability to lower the average diastolic blood pressure to normal levels. Serum total cholesterol and triglyceride levels declined in prazosin-treated patients but increased in hydrochlorothiazide-treated patients, a difference that was statistically significant. No significant weight change, a possible confounding variable, occurred in either group. More patients were unable to tolerate prazosin than were unable to tolerate hydrochlorothiazide (10 of 30 receiving prazosin, compared with three of 32 receiving hydrochlorothiazide). For those able to continue with prazosin, the favorable lipid response appears to be an asset in regard to reducing possible atherogenic effects of treatment.

The effect of 17 alpha-hydroxyprogesterone caproate/oestradiol valerate on the development and outcome of early pregnancies following in vitro fertilization and embryo transfer: a prospective and randomized controlled trial.

A prospective and randomized study was performed to investigate the effect of supportive hormones on the development and outcome of early pregnancies following in vitro fertilization and embryo transfer. Immediately after pregnancies were confirmed endocrinologically on day 15 after oocyte collection, 17 alpha-hydroxyprogesterone caproate and oestradiol valerate (PC/EV) was administered to half of the patients in a randomly controlled trial. One group received supportive treatment until the twelfth week of gestation, whereas the other group received no treatment at all. Both groups were followed up by measurements of serum levels of human chorionic gonadotrophin (HCG), oestradiol and progesterone every three days until day 35, when a first ultrasound examination was carried out to confirm fetal vitality. Subsequently, pregnancies were monitored sonographically at regular intervals. In cases of miscarriage, dilatation and curettage was performed and histology analysed. A total of 120 pregnant patients entered the study: 55 of them received hormone treatment and 65 patients were controls. Within the treatment group 48 (89%) clinically ongoing pregnancies were observed, five (9%) miscarriages occurred after the seventh week of gestation and one preclinical pregnancy was noted. In the control group, 38 (59%) ongoing pregnancies were observed, nine (14%) miscarriages occurred and 17 (27%) preclinical pregnancies were recorded. Two ectopic pregnancies, one in each group, were excluded from evaluation. A significantly higher percentage of pregnancies were intact at 7 weeks of gestation after treatment with PC/EV (p less than or equal to 0.01).

Economic analysis in randomized control trials.

In medical technology assessment, randomized control trials (RCTs) play an important role in determining the relative efficacy of compared treatments. As scarce resources necessitate choosing among options for care, comparing costs of alternative tests, treatments, or programs also becomes important. This study assessed the prevalence and completeness of economic analyses in RCTs published from January 1966 through June 1988. It was found that only 121 of over 50,000 published randomized trials (0.2%) included economic analyses. For a random sample of 51 of these 121 studies, results revealed a mean quality of research score of 0.32 (SD of measurement = 0.14) and a mean economic analysis completeness score of 0.52 (SD = 0.13) on scales of 0 to 1. It was also found that higher economic completeness scores were positively correlated with later dates of publication (r = 0.28, P = 0.046) and with the presence of a statement of study perspective (r = 0.38, P = 0.006). A near-zero correlation between the economic completeness and the quality of research scores was revealed. Also noted were several deficiencies among the economic analyses, including improper allocation of overhead costs, absence of sensitivity analyses, and the fact that only 28% of the 51 studies included some form of aggregation of treatment costs and consequences. Progress in health care depends on accurate assessments of both relative efficacy and costs. The quality of both needs improvement.

Prospective controlled randomized trial of prophylactic antiarrhythmic therapy in postmyocardial infarction patients with asymptomatic ventricular arrhythmias--study design and initial results.

In order to assess the effect of prophylactic antiarrhythmic therapy in asymptomatic patients with persistent complex ventricular ectopic activity after myocardial infarction, a prospective controlled trial was started in 1981 and is still ongoing. Until August 1986, 965 consecutive patients less than or equal to 70 hospitalized for acute myocardial infarction were screened without antiarrhythmic drugs by 24-h ECG before discharge from the hospital. In this group, 238 patients (28%) had ventricular arrhythmias Lown class III-IVb during at least 2 of 24 hours; they were randomly assigned to three treatment groups: (1) individualized antiarrhythmic therapy based on efficacy in multiple 24-h ECGs and drug level determinations (starting with mexiletine or quinidine; n = 79), (2) treatment with low-dose amiodarone (200-400 mg/day after a loading phase; n = 73), and (3) no antiarrhythmic therapy (n = 86). The three groups were comparable regarding age, gender, previous infarction, Q-wave infarction, ejection fraction, as well as incidence and severity of ventricular ectopic activity. Follow-up, including 24-h ECGs, was performed after 3, 6, and 12 months. Based on the results of this study which will be completed by the end of June 1988, it should be possible to estimate the benefit--or harm--of antiarrhythmic drug therapy as well as its cost in postmyocardial infarction patients with asymptomatic ventricular ectopic activity and to decide whether such treatment may improve survival.

Antibiotic prophylaxis in neurosurgery. A randomized controlled trial.

A randomized trial was performed to support the contention that prophylactic antibiotics can reduce the incidence of postoperative neurosurgical wound infections. The regime outlined by Malis was followed. Vancomycin and gentamicin were administered systemically just prior to surgery and streptomycin was added to the irrigating solution. Patients were randomly assigned to two groups: control and treated. The infection rate in the control group was 3.5% and in the treated group 0.5%.

A comparison of sucralfate with placebo in the treatment of esophageal ulcers following therapeutic endoscopic sclerotherapy of esophageal varices--a prospective controlled randomized trial.

In 1984 Roark published the first report of a sucralfate treatment of esophageal ulcers after sclerotherapy. Because this was an uncontrolled trial we planned a prospective double-blind placebo-controlled study with 60 patients. After therapeutic paravariceal injection-sclerotherapy of esophageal varices, patients were randomly treated with sucralfate suspension or placebo. Time of treatment was limited to a maximum of 3 weeks and the dosage of sucralfate was 1 g q.i.d. (Ulcogant-Suspension). Healing was assessed by endoscopy at weekly intervals. Fifty-three patients (25 sucralfate, 28 placebo) were evaluable according to the protocol. No patient left the study because of side effects. At the start of the trial, the patients in the sucralfate group showed a larger ulcer area than the placebo group. There was a tendency to faster healing in the sucralfate group, especially in patients with deeper ulcerations. However, there was no significant difference in global healing between both treatment groups after 3 weeks. Sucralfate suspension may be of value in accelerating the healing process in esophageal ulcers after sclerotherapy, especially in patients with deep ulcers. These results should be confirmed in further trials, in which patients should be stratified with respect to their ulcer volume and severity of liver disease.

Captopril improves hemodynamic response to static exercise in patients with congestive heart failure: a double-blind, placebo-controlled, randomized trial.

Systemic and peripheral hemodynamic response to isometric exercise by handgrip test at 30% maximal voluntary contraction (MVC) for 3 minutes was assessed in 16 patients with congestive heart failure (CHF) after short-term treatment with either captopril or placebo given according to a double-blind, randomized, cross-over sequence. During placebo, isometric exercise increased blood pressure (BP) and total peripheral vascular resistance (TPVR) and decreased cardiac index (CI). Captopril reduced the pressor response to exercise (mean +/- SD) (% systolic: from 14.7 +/- 6 to 11.7 +/- 3; p less than .05/% diastolic: from 12.4 +/- 4 to 8 +/- 3; p less than .005) and increased CI (from 2.3 +/- .6 to 2.6 +/- .9 liters/min/m2; p less than .01) whereas TPVR remained virtually unchanged (from 1479 +/- 597 to 1594 +/- 692 U; NS). The changes in mean BP after exercise were inversely related to the early increase in forearm blood flow (FBF) in exercising forearm during both placebo (r = .67) and captopril (r = .71). The extent of reduction in mean BP response after captopril was inversely related to the extra increase in exercising FBF determined by the drug when compared to placebo (r = .73). We conclude that captopril is able to improve the hemodynamic response to static exercise in patients with CHF, probably by increasing the blood supply to exercising muscles during contraction, thus blunting the extent of reflex pressor response.

Cyclosporin-induced remission of IDDM after early intervention. Association of 1 yr of cyclosporin treatment with enhanced insulin secretion. The Canadian-European Randomized Control Trial Group.

A randomized double-blind placebo-controlled trial was undertaken to determine whether cyclosporin enhances remission of insulin-dependent diabetes mellitus (IDDM) through the 1st yr after diagnosis. Dosage with insulin was minimized with target control of blood glucose levels less than or equal to 7.8 mM (140 mg/dl) before meals. Metabolic control was evaluated by serial determinations of glycosylated hemoglobin levels, and endogenous secretion of insulin was evaluated by determination of the levels of glucagon-stimulated insulin-connecting peptide (CP) in the plasma at 3-mo intervals. A compound definition of remission required a glucagon-stimulated CP level in plasma greater than or equal to 0.6 nM or a non-insulin-receiving state (NIR) in which target control of glycemia was maintained without administration of insulin. A clinical definition of remission required only the NIR state as defined. One hundred eighty-eight patients aged 10-35 yr entered the study within 6 wk of initiation of insulin therapy and within 14 wk of onset of symptoms and were studied for 1 yr. There were no significant differences in metabolic control between the two treatment groups during the study. The anticipated adverse effects of cyclosporin were not more frequent or severe than in other experience with the drug, but histological changes attributable to cyclosporin were present in some kidney biopsies obtained from selected patients after 1 yr. At 1 yr, by the compound definition, 33% of the cyclosporin-group and 21% of the placebo-group patients were in remission, when the corresponding rates for NIR remissions were 24 and 10%.(ABSTRACT TRUNCATED AT 250 WORDS)

Prospective, controlled, randomized trial of naloxone infusion in early hyperdynamic septic shock.

To determine whether naloxone infusion is efficacious in severe hyperdynamic septic shock, we conducted a prospective study of 22 patients randomly assigned to a naloxone or placebo group. Patients were treated 12 +/- 2 h (SEM) after the onset of shock, with a mean arterial pressure (MAP) of 63 +/- 3 mm Hg. All patients had clinical evidence of an infectious process and required dopamine 20 +/- 2 micrograms/kg.min. Five (46%) of 11 patients in the naloxone group and one (9%) of the other 11 patients in the placebo group responded clinically. The MAP among the five responders increased from 62 +/- 5 to 89 +/- 4 mm Hg within 20 min of naloxone treatment (p less than .01). This favorable hemodynamic response was sustained throughout the patients' clinical course. In contrast, the MAP did not change significantly in the nonresponders who received naloxone, nor did it change in the placebo group. More patients in the naloxone group than in the placebo group received steroids concurrently. Survival rate was 100% in those who responded to naloxone clinically. However, overall survival rate in each group was essentially the same. No adverse effects were observed, except for mild agitation in some of the patients receiving naloxone. We conclude that naloxone infusion is clinically efficacious in improving the hemodynamic profile of a subgroup of patients with severe early hyperdynamic septic shock, but does not appear to improve the overall survival rate.
