Static and Dynamic Effects of Stroke Onset on Depressive Symptoms in Middle-Aged and Older Adults: Evidence Across 21 Countries.
Synthesis in Journal of the American Heart Association, 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
backgroundStroke and depressive symptoms are significant public health concerns worldwide; however, their causal relationship remains unclear. Therefore, there is a need for comprehensive multicountry studies that examine both static and dynamic effects over time. METHODS AND
resultsWe conducted a pooled multicohort study across 21 countries using nationally representative longitudinal data sets. Our sample was restricted to individuals aged ≥50 years who were followed for at least 2 waves. First, the fixed-effects model in conjunction with propensity score matching was used to analyze the static effect of stroke onset on depressive symptoms. Next, by using an event study methodology, we delved into the dynamic relationship. Furthermore, meta-analyses and multilevel model were conducted to assess heterogeneity and explore the moderating role of national-level indicators. Our study revealed a statistically significant and robust causal linkage between stroke onset and depressive symptoms. Further analysis highlighted both the anticipatory effects of stroke occurrence and the sustained, substantive impact on depressive symptoms over more than a decade. Meta-regression analyses indicated that countries with higher mortality from noncommunicable diseases exhibited attenuated effect sizes. Furthermore, we observed a modest moderating effect of mortality from noncommunicable diseases and life expectancy.
conclusionsThis research underscores the complex relationship between stroke and depressive symptoms, highlighting the need to further identify underlying mechanisms.
