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
backgroundThe European Society of Cardiology (ESC) guidelines for peripheral artery disease recommend antithrombotic strategies based on high ischemic risk (HIR) and high bleeding risk (HBR) criteria. However, their prognostic value in patients with lower extremity artery disease (LEAD) undergoing endovascular therapy (EVT) remains unclear. Therefore, we aimed to evaluate whether the number of ESC-HIR and ESC-HBR criteria met was associated with clinical outcomes in Japanese patients treated with EVT.
methodsWe retrospectively analyzed 333 patients with LEAD who underwent EVT at a single center. ESC-HIR and ESC-HBR scores were separately calculated by assigning 1 point to each criterion and were evaluated independently. The primary outcome was major adverse cardiovascular and limb events (MACLE), defined as the composite of cardiovascular death, myocardial infarction, ischemic stroke, acute limb ischemia, and major amputation.
resultsOver a median follow-up of 1175 days, 93 patients had MACLE. Higher ESC-HIR and ESC-HBR scores were associated with increased MACLE incidence (log-rank p = 0.022 and p < 0.001). In the multivariable analysis, ESC-HBR remained independently associated with MACLE (hazard ratio [HR], 1.59; 95% confidence interval [CI], 1.21-2.10; p = 0.001), whereas ESC-HIR showed a trend toward association (HR, 1.23; 95% CI, 0.99-1.52; p = 0.061). Time-dependent receiver operating characteristic analysis showed modest discrimination for both scores.
conclusionsESC-HIR and ESC-HBR scores showed limited prognostic performance for MACLE in Japanese patients undergoing EVT for LEAD. Both scores may be useful for risk stratification in Japanese patients; however, these findings require validation in larger studies.
