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

backgroundGender differences in clinical outcomes after percutaneous coronary intervention (PCI) among different age groups are controversial in the era of drug-eluting stents, especially among the Asian population who are at higher risk for bleeding complications. METHODS AND

resultsWe analyzed data from 10,220 patients who underwent PCI procedures performed at 14 Japanese hospitals from September 2008 to April 2013. A total of 2,106 (20.6%) patients were women. Women were older (72.7±9.7 vs 66.6±10.8 years, p<0.001), and had a lower body mass index (23.4±4.0 vs 24.3±3.5, p<0.001), with a higher prevalence of hypertension (p<0.001), hyperlipidemia (p<0.001), insulin-dependent diabetes (p<0.001), renal failure (p<0.001), and heart failure (p<0.001) compared with men. Men tended to have more bifurcation lesions (p = 0.003) and chronic totally occluded lesions (p<0.001) than women. Crude overall complications (14.8% vs 9.5%, p<0.001) and the rate of bleeding complications (5.3% vs 2.8%, p<0.001) were significantly higher in women than in men. On multivariate analysis in the total cohort, female sex was an independent predictor of overall complications (OR, 1.47; 95% CI, 1.26-1.71; p<0.001) and bleeding complications (OR, 1.74; 95% CI, 1.36-2.24; p<0.001) after adjustment for confounding variables. A similar trend was observed across the middle-aged group (≥55 and <75 years) and old age group (≥75 years).

conclusionsWomen are at higher risk than men for post-procedural complications after PCI, regardless of age.
