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

objectivesThe purpose of this study was to examine the incidence of nuisance bleeding after AMI and its impact on QOL.

backgroundProlonged dual antiplatelet therapy (DAPT) is recommended after acute myocardial infarction (AMI) to reduce ischemic events, but it is associated with increased rates of major and minor bleeding. The incidence of even lesser degrees of post-discharge "nuisance" bleeding with DAPT and its impact on quality of life (QOL) are unknown.

methodsData from the 24-center TRIUMPH (Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status) study of 3,560 patients, who were interviewed at 1, 6, and 12 months after AMI, were used to investigate the incidence of nuisance bleeding (defined as Bleeding Academic Research Consortium type 1). Baseline characteristics associated with "nuisance" bleeding and its association with QOL, as measured by the EuroQol 5 Dimension visual analog scale, and subsequent re-hospitalization were examined.

resultsNuisance (Bleeding Academic Research Consortium type 1) bleeding occurred in 1,335 patients (37.5%) over the 12 months after AMI. After adjusting for baseline bleeding and mortality risk, ongoing DAPT was the strongest predictor of nuisance bleeding (rate ratio [RR]: 1.44, 95% confidence interval [CI]: 1.17 to 1.76 at 1 month; RR: 1.89, 95% CI: 1.35 to 2.65 at 6 months; and RR: 1.39, 95% CI: 1.08 to 1.79 at 12 months; p < 0.01 for all comparisons). Nuisance bleeding at 1 month was independently associated with a decrement in QOL at 1 month (-2.81 points on EuroQol 5 Dimension visual analog scale; 95% CI: 1.09 to 5.64) and nonsignificantly toward higher re-hospitalization (hazard ratio: 1.20; 95% CI: 0.95 to 1.52).

conclusionsNuisance bleeding is common in the year after AMI, associated with ongoing use of DAPT, and independently associated with worse QOL. Improved selection of patients for prolonged DAPT may help minimize the incidence and adverse consequences of nuisance bleeding.
