Reduced frequency of high cholesterol levels among patients with intracerebral haemorrhage.

To determine whether a relationship exists between high cholesterol levels and intracerebral haemorrhage (ICH) a case-control study was undertaken on 331 consecutive cases of first-episode primary ICH, verified by computed tomography, and 331 age- and sex-matched community controls. Using conditional logistic regression the adjusted odds ratio (OR) of ICH among individuals reporting a high cholesterol level was 0.45 [95% confidence interval (CI), 0.28-0.73]. A similar finding was observed when the analysis was limited to those using cholesterol-lowering drugs (OR 0.25; 95% CI, 0.08-0.80). These data provide support for an inverse relationship between high cholesterol levels and ICH. When considered together with previous findings, in which low cholesterol levels have been associated with an increased risk of haemorrhagic stroke, these data provide evidence that this inverse relationship may extend into a higher range of cholesterol values.

Inter-rater reliability of stroke sub-type classification by neurologists and nurses within a community-based stroke incidence study.

The stroke classification developed for use in the Oxfordshire Community Stroke Project (OCSP) is simple, clinically meaningful and requires no investigations. However, its inter-rater reliability in a community setting is unknown. We aimed to assess the inter-rater reliability of this classification among neurologists and nurses within a community-based stroke incidence study. Fifty-four stroke patients with cerebral infarction who were registered in the North East Melbourne Stroke Incidence Study (NEMESIS) were assigned OCSP classifications by two neurologists and one of seven research nurses. There was moderate agreement between neurologists (kappa = 0.53), fair agreement between neurologist 1 and nurse (kappa = 0.31) and moderate agreement between neurologist 2 and nurse (kappa = 0.45). Disagreement about the neurological signs was an important reason for classification differences. The OCSP classification can be easily applied in a community setting with moderate inter-rater reliability and is thus a useful instrument for commun ity-based epidemiological studies.
