Determinants of Post-Stroke Cognitive Impairment After Acute Ischemic Stroke: A Systematic Review and Meta-Analysis.
Review in Neuropsychiatric disease and treatment, 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: Acute ischemic stroke (AIS) is frequently complicated by post-stroke cognitive impairment (PSCI), which significantly affects long-term prognosis and quality of life. However, the evidence regarding its risk factors remains inconsistent. Methods: A systematic search was conducted in PubMed, Embase, Cochrane Library, and Web of Science up to December 30, 2025. Observational studies evaluating risk factors for PSCI after AIS were included. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using fixed- or random-effects models. Heterogeneity, sensitivity analyses, and publication bias were assessed. Results: Fifteen studies involving 30,022 participants were included. Age >75 years (OR = 1.07, 95% CI: 1.04-1.10), female sex (OR = 1.72, 95% CI: 1.41-2.10), diabetes (OR = 1.76, 95% CI: 1.29-2.40), elevated C-reactive protein (CRP; OR = 1.36, 95% CI: 1.14-1.62), and lower educational level (OR = 1.24, 95% CI: 1.12-1.38) were significantly associated with an increased risk of PSCI after AIS. Substantial heterogeneity was observed for some predictors, particularly age ( Conclusion: Several factors, including advanced age, female sex, diabetes, elevated CRP, and lower educational level, were associated with an increased risk of PSCI after AIS. These findings may support risk stratification and early monitoring strategies. However, the substantial heterogeneity observed for some predictors should be considered when interpreting the pooled estimates. Further prospective studies are needed to confirm these associations and clarify causal relationships.
