No sex difference in the association of pre-stroke physical activity with functional independence after ischemic stroke.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Whether physical activity is associated with functional outcomes from ischemic stroke remains poorly understood. We aimed to explore the association of pre-stroke physical activity and functional outcomes in patients with acute ischemic stroke according to sex. Pre-stroke physical activity was assessed using a four-level questionnaire named Saltin-Grimby Physical Activity Level Scale (SGPALS). Our primary outcome was functional independence, defined as a modified Rankin Scale (mRS) score of 0-2 three months after stroke onset. The secondary outcome was the shift in the mRS score at 3 and 6 months. A prospective cohort study design was used to estimate the multivariable-adjusted odds of functional independence with pre-stroke physical activity. We analyzed 257 men and 142 women participants, including 230 physically inactive and 169 active ones in the final analysis. Physical active participants were at a higher odds of achieving functional independence at 3 months (adjusted OR 4.14, 95% CI 2.35-7.31; adjusted common odds ratio (cOR) 2.38, 95% CI 1.60-3.56). When stratified by sex adjusted point estimates from logistic regression models indicated that pre-stroke physical activity was significantly associated with 3-month functional independence in both men (adjusted OR 4.75, 95%CI 2.23-10.09; adjusted cOR 2.70, 95% CI 1.63-4.51) and women (adjusted OR 3.64, 95% CI 1.44-9.18; adjusted cOR 2.10, 95% CI 1.01-4.43). This study showed an association between physical activity and functional independence 3 months after ischemic stroke. Moreover, no indication of sex difference in this association were observed.
