Temporal Trends in the Use of Primary Prevention Medications at Stroke Admission.

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
introductionOver 80% of strokes are preventable through appropriate management of cardiovascular risk factors including pharmacotherapy interventions (antihypertensive and lipid-lowering medications). In this study, we aimed to: (i) determine the proportion of patients reported to use primary prevention medications before their first stroke admission and (ii) compare differences in the use of these medications over time, by sex and age.
methodsFor this study, we used secondary analysis of cross-sectional clinical data from the Stroke Foundation biennial National Stroke Audit - Acute Services (2007-2019; 7 cycles). Data collected for adult patients with first-ever stroke included demographics (age, sex), stroke presentation information (stroke type), and medical history (risk factors, use of primary prevention medications, pre-stroke independence [modified Rankin Scale]). Patient data were summarized with descriptive statistics. Adjusted proportions (year, age, sex, pre-stroke independence) of medication use were derived from multivariable logistic regression models. Proportions were compared across audit years using Cochran-Armitage tests for linear trends (p
resultsOf 17,944 patients (median age 74.6 years; 54.5% male), most had a history of hypertension (73.0%), and 48.4% had hypercholesterolemia before stroke. Significant increases in the use of antihypertensive medications were observed over time, particularly for women (all ages p
conclusionThe use of primary prevention medications before first stroke increased over time in the audited stroke episodes from participating Australian hospitals. There were disparities across sex and age groups, indicating opportunities to improve equitable access to guideline-recommended care to enhance primary stroke prevention.
