Association between high plasma levels of legumain and cardiovascular events in patients undergoing coronary angiography.
Article in Heart and vessels, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Degradation of vascular extracellular matrix is important in atherosclerosis. Cysteine protease legumain is upregulated in atherosclerotic plaques. We recently reported that plasma legumain levels are high in patients with complex coronary lesions. This study investigated the association between legumain levels and cardiovascular events in 372 patients undergoing coronary angiography. Patients with acute coronary syndrome were excluded. Of the 372 patients, 225 had coronary artery disease (CAD). During a mean follow-up of 7.0 ± 4.3 years, cardiovascular events occured in 62 patients. Compared with 310 patients without events, 62 with events tended to have higher prevalence of complex lesions (15% vs. 10%). Notably, patients with events had higher legumain levels (median 5.51 vs. 4.90 ng/mL, P < 0.01) than those without events. A Kaplan-Meier analysis showed lower event-free survival in patients with legumain > 5.0 ng/mL than in those with ≤ 5.0 ng/mL (P < 0.01). In multivariate Cox regression analysis, legumain level was an independent predictor of cardiovascular events. The hazard ratio for legumain > 5.0 ng/mL for cardiovascular events was 2.18 (95%CI = 1.27-3.77, P < 0.01). Only among 225 patients with CAD, patients with events had higher legumain levels (5.49 vs. 4.73 ng/mL) than without events (P < 0.02). Legumain level was also a predictor of cardiovascular events in patients with CAD. Thus, high plasma legumain levels were associated with an increased risk of cardiovascular events in patients undergoing coronary angiography and those with stable CAD.
