Evaluating Aspirin's Efficacy for Primary Prevention in Cardiovascular and Cerebrovascular Disease: Insights from a Nationwide Cohort Study.
Article in Clinics and practice, 2024. 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
backgroundThe effectiveness of aspirin for the primary prevention of cerebro-cardiovascular diseases in Koreans remains unclear. Therefore, we evaluated the preventive effects of low-dose aspirin (equal or less than 100 mg) on cerebro-cardiovascular events.
methodWe conducted a retrospective cohort study using the National Sample Cohort dataset. From the 1,106,580 individuals eligible in 2004, we selected 200 individuals (47% male and 22.5% aged 65 or older) who consistently received low-dose aspirin from 2004 to 2013 for inclusion in the aspirin cohort. Participants for the control cohort, who did not use aspirin, were selected through propensity score matching based on variables.
resultWe compared the incidences of endpoints (acute myocardial infarction, cerebral infarction, gastrointestinal hemorrhage, and cerebral hemorrhage) between the aspirin group and the non-aspirin group over the 9-year follow-up period. There was no significant difference in the incidence rates of acute myocardial infarction, cerebral infarction, gastrointestinal hemorrhage, or cerebral hemorrhage between the aspirin and non-aspirin groups. Low-dose aspirin for primary prevention in Koreans did not reduce myocardial or cerebral infarctions and did not increase the risk of gastrointestinal or cerebral hemorrhage.
conclusionTherefore, we suggest that aspirin for primary prevention should be used cautiously and tailored to the individual's baseline cardiovascular risk.
