Acute Care, Secondary Prevention, and Outcomes after Ischaemic and Haemorrhagic Stroke in Men and Women: A Data-Linkage Study.

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
introductionThere is evidence that sex differences exist in stroke presentation, risk factors, severity, treatment, and outcomes. To further understand this, we explored how sex differences influence acute stroke management, secondary prevention prescribing, and mortality outcomes in a well-characterised cohort of first-ever stroke patients in Scotland.
methodsThis is a retrospective, population-based, data-linkage study of stroke admissions to acute care hospitals in Scotland between January 1, 2011, and December 31, 2018. Data sources included the Scottish Stroke Care Audit (SSCA), the Prescribing Information System (PIS), the Scottish Morbidity Record 01 (SMR01), and the National Records of Scotland (NRS) death records. Multivariable logistic regression was used to explore the association between patient sex, acute stroke care, and secondary prevention prescribing, while Cox proportional hazards models were used to explore the association between patient sex and all-cause mortality up to 1 year after index event.
resultsThis study included 5,901 patients with a first-ever intracerebral haemorrhage (ICH) and 47,087 patients with a first-ever acute ischaemic stroke (AIS). After an ICH, women had significantly lower odds of receiving all components of the stroke care bundle (adjusted odds ratio [aOR], 0.78; 95% confidence interval [CI], 0.69-0.87) and were less likely to be prescribed antihypertensives within 90 days after discharge to the usual place of residence (aOR, 0.78; 95% CI, 0.63-0.97). There was no sex difference in stroke care bundle achievement for those admitted with AIS; however, women had significantly lower odds of receiving antihypertensives, lipid-lowering drugs, or oral anticoagulants after discharge. The risk of all-cause mortality was lower in women at 1 year after both ICH (adjusted hazard ratio [aHR], 0.90; 95% CI, 0.83-0.98) and AIS (aHR, 0.91; 95% CI, 0.87-0.95) after adjusting for potential confounders.
conclusionThe sex differences in stroke treatment and outcomes may be partly explained by the older age of women at the time of stroke, which influences stroke presentation, severity, and prognosis. However, following adjustment, women had a reduced risk of all-cause mortality after both ICH and AIS.
