Sex Differences in Stroke Risk Factors and Mechanisms in a Multi-Ethnic Asian Population.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPrevious studies have reported sex differences in stroke. There are few Asian studies. This study was performed to investigate sex differences in stroke risk factors and mechanisms in a multi-ethnic Asian population.
methodsData on patients admitted to Raffles Hospital for stroke were analysed. Data were extracted on sex, age, hypertension, diabetes mellitus (DM), hyperlipidaemia, smoking, heart disease, and prior cerebrovascular events (pCeVD). Stroke was subtyped into haemorrhagic stroke (HS) or ischaemic stroke (IS) based on brain scan. IS mechanism was categorised using Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, while the clinical syndrome by Oxfordshire Community Stroke Project (OCSP) classification.
resultsData were collected on 1165 patients, mean age 65.6 ± 12.9 yr; 47.4% female, 83.0% Chinese, with hypertension (63.5%) and hyperlipidaemia (60.3%) being the most common risk factors. HS comprised 23.5%. On regression analysis, compared to males, females had older age (OR 1.03, 95%CI 1.02-10.4) and DM (OR 1.60, 95%CI 1.11-2.30), but less smoking (OR 0.09, 95%CI 0.07-0.13), pCeVD (OR 0.67, 95%CI 0.49-0.93), and HS (OR 0.71, 95%CI 0.51-0.98). There were no differences in HS mechanisms, or IS mechanisms or syndromes. Sex-ethnic differences were found (
conclusionsThis study corroborates previous studies of significantly older age and more diabetes mellitus, but less smoking and haemorrhagic stroke among female stroke patients compared to males; differences in HS and IS mechanisms were not found. Novel in this study is that sex-ethnicity differences were found. Future studies should prospectively validate these sex/ethnic differences.
