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
backgroundPatients at high ischemic or bleeding risk after percutaneous coronary intervention (PCI) require protection against thrombotic events with dual antiplatelet therapy (DAPT) while avoiding bleeding. Although guidelines recommend 12-month DAPT after acute coronary syndrome (ACS), recent trials have tested the safety of early aspirin withdrawal with potent P2Y12-inhibitor monotherapy. METHODS AND
findingsWe performed a meta-analysis of randomized trials (from inception through August 2025) comparing early aspirin withdrawal (≤3 months) with transition to ticagrelor- or prasugrel-monotherapy versus continued DAPT. Co-primary outcomes were myocardial infarction (MI) and clinically relevant bleeding. Prespecified timing analyses stratified the comparison versus DAPT by aspirin timing: immediate (aspirin noninitiation or in-hospital cessation) and early (post-discharge discontinuation within 3 months). Bayesian models quantified risk-stratified probabilities of benefit and harm; trial sequential analysis (TSA) assessed conclusiveness of evidence. Seven trials (n = 27,743) were included. P2Y12-inhibitor monotherapy reduced bleeding (HR = 0.55, 95% CI [0.42, 0.71]; p < 0.001) without significantly increasing MI overall (HR = 1.11, 95% CI [0.91, 1.35]; p = 0.31), death, stroke, or stent thrombosis. Immediate aspirin noninitiation/cessation increased MI (HR = 1.41, 95% CI [1.01, 1.97]; p = 0.04), whereas early discontinuation did not (HR = 0.97, 95% CI [0.76, 1.24]; p = 0.82). TSA indicated conclusiveness for bleeding benefit and futility for an MI excess. Analyses restricted to ACS confirmed the overall results. Bayesian analyses corroborated these effects and identified risk-aligned timing: in high bleeding risk, ≤1-month aspirin discontinuation yielded a 100% posterior probability of bleeding benefit (NNT = 12) and 70% probability of MI-safety; in high ischemic risk, 3-month aspirin discontinuation yielded 100% probability of bleeding benefit (NNT = 57) and 86% probability of MI-safety. Limitations include aggregate data only and limited precision for the immediate aspirin withdrawal subgroup.
conclusionsAmong high-risk post-PCI patients on ticagrelor/prasugrel, discontinuing aspirin within 3 months reduces bleeding without an ischemic trade-off versus DAPT. Immediate aspirin noninitiation or cessation should be avoided; timing should be individualized to bleeding and ischemic risk. PROSPERO: CRD420251167706.
