Oxiracetam and physical activity in preventing cognitive decline after stroke: A multicenter, randomized controlled trial.
Article in European stroke journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionThis multicenter, double-blind, placebo-controlled trial, commissioned by South Korea's Ministry of Food and Drug Safety, evaluated the effect of oxiracetam for preventing post-stroke cognitive impairment (PSCI) and explored potential interaction with physical activity using neuroimaging. PATIENTS AND
methodsPatients at high risk of PSCI, reporting subjective cognitive decline ⩾3 months after stroke, were randomized 1:1 to receive oxiracetam or placebo for 36 weeks. Physical activity was tracked via wrist-worn actigraphy. Coprimary endpoints were changes in Mini-Mental State Examination (MMSE) and Clinical Dementia Rating-Sum of Boxes (CDR-SB). Secondary outcomes included neuropsychological assessments and resting-state functional magnetic resonance imaging network metrics.
resultsOf 500 enrolled participants (mean age 68.9 years; median 32 months post-stroke), 457 completed the study. There were no statistically significant differences between groups in changes in MMSE (oxiracetam: +0.13 ± 2.27 vs placebo: +0.27 ± 2.09; DISCUSSION AND
conclusionOxiracetam did not demonstrate benefit in preventing PSCI in high-risk patients. These findings support the recent regulatory decision to suspend its use in South Korea.
