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

Introduction: Cuproptosis due to copper overload is a contributor to the progression of cardiovascular diseases, especially heart failure (HF) after acute myocardial infarction (AMI). Solute carrier family 31 member 1 (SLC31A1) is a major Cu2+ transporter responsible for intracellular Cu2+ uptake. In this study, we investigated the role and detailed mechanism of SLC31A1 in post-AMI HF. Methods: Mouse left anterior descending coronary artery was ligated to produce an Results: SLC31A1 was up-regulated in macrophages of mice with post-AMI HF , while its knockdown prevented cardiomyocyte apoptosis and post-AMI HF. Mechanistically, SLC31A1 knockdown regulated copper metabolism imbalance to reduce macrophage cuproptosis and HMGB1 release, attenuating inflammatory responses and the resultant cardiomyocyte apoptosis. This could be explained by NLRP3 inflammasome inactivation. Meanwhile, ATTM reduced macrophage cuproptosis and cardiomyocyte apoptosis. These results were reproduced in Discussion: SLC31A1 plays a disease-promoting role in HF after AMI by activating NLRP3/HMGB1-dependent macrophage cuproptosis, which is expected to be a potential biomarker for HF.
