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

backgroundClopidogrel has emerged as a promising alternative to aspirin monotherapy for maintenance therapy after percutaneous coronary intervention (PCI); however, the optimal antiplatelet strategy according to sex remains controversial.

aimsWe aimed to investigate whether the treatment effect of antiplatelet therapy differs according to sex.

methodsThis study was a prespecified substudy of the SMART-CHOICE 3 trial. Patients at high risk of recurrent ischaemic events who had completed the standard duration of dual antiplatelet therapy after PCI were randomly assigned to receive clopidogrel or aspirin monotherapy. The primary endpoint was a composite of all-cause death, myocardial infarction, or stroke.

resultsA total of 5,506 patients, including 1,002 females and 4,504 males, were enrolled in South Korea. Females had a higher risk profile than males; however, the incidence of the primary endpoint did not differ significantly between females and males (6.7% vs 5.2%, adjusted hazard ratio [HR] 0.89, 95% confidence interval [CI]: 0.62-1.28; p=0.537). Clopidogrel, compared with aspirin, significantly reduced the primary endpoint in females (4.3% vs 9.4%, adjusted HR 0.45, 95% CI: 0.24-0.85; p=0.014) but not in males (4.4% vs 6.0%, adjusted HR 0.77, 95% CI: 0.56-1.07; p=0.116). There was no significant interaction between sex and the antiplatelet therapy (p for interaction=0.288).

conclusionsIn patients with remote PCI and a high risk of recurrent ischaemic events, clopidogrel monotherapy showed a directionally consistent reduction in the composite endpoint of all-cause death, myocardial infarction, or stroke compared with aspirin in both females and males. No significant sex-by-treatment interaction was observed, supporting the consistency of the treatment effect across sexes.
