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
Myocardial ischemia-reperfusion injury is accompanied by ferroptosis mediated by reactive oxygen species and iron ions, which aggravates myocardial tissue damage. The present study aims to explore the molecular mechanism underlying the mitigating effects f PCSK9 on myocardial ischemia-reperfusion injury. MI/R rat model and OGD/R induced H9c2 model were established. The interaction between PCSK9 inhibitor and LRP8 was predicted by STRING database and verified by Immunoprecipitation assay experiment. CCK-8 kit results confirmed that PCSK9 inhibitor effectively protected against cardiomyocyte damage induced by OGD/R. TTC and histological examination via H&E staining revealed a significant alleviation of myocardial infarction and pathological alterations upon treatment with the PCSK9 inhibitor. Besides, DCFH-DA staining and biochemical kit results showed that PCSK9 inhibitor could regulate the changes of ferroptosis related indicators [ROS, iron level, MDA, SOD] and inhibit ferroptosis. Rescue experiments showed that PCSK9 inhibitors targeted LRP8 expression and inhibited GPX4/ROS-mediated ferroptosis in I/R-induced rats. Our study suggested that PCSK9 inhibitors could attenuate myocardial I/R injury, with the underlying mechanism intimately tied to the targeted modulation of LRP8/GPX4-mediated ferroptosis.
