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
Endotrophin is a matrikine released from the C-terminus of the alpha-3 chain of type VI collagen, gaining increasing attention both as a biomarker and as a therapeutic target in the cardiometabolic space. So far, it has been quantified in circulation by the PRO-C6 assay, which detects different-sized proteolytic fragments of the C-terminus, including endotrophin. Here, we developed and evaluated a novel immunoassay targeting the full-length endotrophin, explored its biological relevance in two clinical cohorts of HFpEF, and investigated its potential as a prognostic biomarker. Increased circulating Endotrophin levels were associated with cardiovascular and all-cause mortality in both cohorts. When adjusting for relevant confounders, Endotrophin remained independently associated with both endpoints only in cohort 1. This work emphasizes the importance of the extracellular matrix in disease, confirms the prognostic value of endotrophin, and provides a novel tool for further exploration of its biological role.
