An Aspirin-Free Strategy for Patients Undergoing Staged Percutaneous Coronary Intervention - A Subgroup Analysis of the STOPDAPT-3 Trial.

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
Background: No previous studies have evaluated the effect of an aspirin-free strategy for patients undergoing staged percutaneous coronary intervention (PCI). Methods and Results: We conducted a post hoc subgroup analysis in patients undergoing staged PCI within 1 month in STOPDAPT-3 (n=6,002), which randomly compared prasugrel monotherapy with dual antiplatelet therapy (DAPT) in patients with acute coronary syndrome or high bleeding risk. The co-primary endpoints were major bleeding (Bleeding Academic Research Consortium 3 or 5) and cardiovascular events (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or stroke) at 1 month. There were 814 patients undergoing staged PCI within 1 month (no-aspirin group, n=401; DAPT group, n=413). The median interval from randomization to the first staged PCI was 8 (interquartile range 5-13) days. More than 90% of the patients received assigned antiplatelet agents at all staged PCI procedures. The effect of no-aspirin relative to DAPT was not different for the co-primary bleeding (3.74% vs. 1.94%; HR 1.94; 95% CI 0.82-4.57) and cardiovascular (3.49% vs. 2.42%; HR 1.44; 95% CI 0.64-3.25) endpoints. The no-aspirin group compared with the DAPT group had a numerically higher incidence of the co-primary cardiovascular endpoint, which occurred after the first staged PCI procedure (2.49% vs. 1.21%; HR 2.07; 95% CI 0.71-6.05). Conclusions: An aspirin-free prasugrel monotherapy relative to DAPT had numerically higher risks of cardiovascular and major bleeding events in patients undergoing staged PCI at 1 month.
