1 · What the graph read from it

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.

2 · The registry

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

backgroundAntiplatelet therapy is a cornerstone in the management of atherosclerotic cardiovascular disease. However, the risk profile of central nervous system (CNS) hematomas associated with antiplatelet agents remains incompletely characterized.

methodsWe analyzed CNS-related hematoma adverse event (hAE) reports across the four antiplatelet drugs, using data from the US Food and Drug Administration Adverse Event Reporting System (FAERS) and the World Health Organization's VigiAccess databases. Disproportionality analysis was conducted to identify positive signals. Stratified analysis assessed risk differentials by age and gender, time-to-onset analysis characterized temporal patterns, and a global assessment of the evidence was established.

resultsA total of 2274 CNS-related hAE reports were identified in FAERS and 7229 in VigiAccess. All four antiplatelet drugs demonstrated significant disproportionality signals, with clopidogrel [FAERS: reporting odds ratio (ROR), 26.79; VigiAccess: ROR: 36.69] and aspirin (FAERS: ROR, 22.06; VigiAccess: ROR, 40.13) showing the strongest associations, followed by prasugrel (FAERS: ROR, 16.91; VigiAccess: ROR, 24.02), and ticagrelor (FAERS: ROR, 8.07; VigiAccess: ROR, 9.80). Subdural hematomas were the most frequently reported subtype (FAERS: 63.11%; VigiAccess: 62.72%). Female patients exhibited stronger signals than males across all drugs. All antiplatelet drugs revealed early failure-type temporal profiles, with median onset times ranging from 12.0 days for ticagrelor to 442.5 days for aspirin ( P < 0.001).

conclusionsWe found a disproportionately significant association between antiplatelet therapy and CNS-related hematomas, with distinct patterns observed across drug types, patient demographics, and temporal profiles. These findings provide critical insights to inform risk stratification, clinical decision-making, and safety monitoring in patients undergoing antiplatelet therapy.
