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

purposeTo evaluate the efficacy and safety of early aspirin discontinuation followed by P2Y12 inhibitor monotherapy versus standard dual antiplatelet therapy (DAPT) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).

methodsThis systematic review and meta-analysis followed PRISMA 2020 guidelines and a prespecified protocol registered in PROSPERO (CRD420261293472). MEDLINE, Embase, Scopus, and CENTRAL were searched through December 2025 for randomized controlled trials comparing early aspirin discontinuation (≤ 3 months) with standard DAPT in ACS patients undergoing PCI with drug-eluting stents. Two reviewers independently conducted study selection, data extraction, and risk of bias assessment (Cochrane RoB 2.0). Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were estimated using a random-effects model.

resultsSeven trials including 20,501 patients (10,246 early discontinuation; 10,255 standard DAPT) were analyzed. Early aspirin discontinuation significantly reduced bleeding (RR, 0.46; 95% CI, 0.36-0.60; p < 0.001; I²=21.9%). There was no significant difference in major adverse cardiovascular events (RR, 0.98; 95% CI, 0.77-1.26) or in myocardial infarction, stroke, repeat revascularization, or all-cause mortality. However, early aspirin discontinuation was associated with an increased risk of stent thrombosis (RR, 1.72; 95% CI, 1.07-2.78). In trials with aspirin discontinuation within 1 month, bleeding reduction remained substantial, with numerically higher but nonsignificant ischemic outcomes.

conclusionIn ACS patients undergoing PCI, early aspirin discontinuation reduces bleeding without a statistically significant increase in overall ischemic events; however, a significant increase in stent thrombosis was observed. These results support individualized decision-making, particularly favoring patients at high bleeding risk and low thrombotic risk treated with potent P2Y12 inhibitors. Further adequately powered studies focused on rare ischemic outcomes, including stent thrombosis, are warranted.
