Mitigating Stroke Risk in Type 2 Diabetes Through Physical Activity: A Nationwide Population-Based Study in Sweden.
Article in Journal of stroke, 2026. 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
Background and Purpose: Type 2 diabetes (T2DM) is associated with elevated stroke risk. Physical activity may attenuate this excess risk, but large-scale population evidence is limited. This study evaluated whether physical activity mitigates excess stroke risk in individuals with T2DM compared with age- and sex-matched individuals without diabetes. Methods: All adults with T2DM registered in the Swedish National Diabetes Register between 2010 and 2019 were included and matched 1:3 to individuals without diabetes based on age and sex. Participants were stratified into five groups according to physical activity. Stroke incidence was estimated using Kaplan-Meier curves, and Cox proportional hazards models calculated adjusted hazard ratios (HRs) for ischemic and hemorrhagic stroke. Robustness was assessed using competing risks regression. Results: The cohort included 369,704 individuals with T2DM (mean [standard deviation] age, 64.3 [12.3] years; 156,729 female individuals [42.4%]) and 1,109,112 matched individuals without diabetes. The adjusted HR for ischemic stroke in inactive individuals with T2DM compared with individuals without diabetes was 1.36 (95% confidence interval [CI] 1.23-1.50), declining with higher activity and becoming non-significant among those active ≥3 times/week (HR 1.05, 95% CI 0.96-1.15). The elevated ischemic stroke risk at higher glycated hemoglobin levels was attenuated in individuals with higher physical activity. Conclusions: Higher physical activity levels were associated with reduced stroke risk in individuals with T2DM. Those active at least three times weekly had stroke risk comparable to individuals without diabetes of the same age and sex. Promoting physical activity should be an integral component of diabetes care and stroke prevention.
