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
This study aimed to investigate the cardioprotective role and underlying mechanisms of the endogenous metabolite mesaconate in both acute and chronic cardiovascular disease models, with a focus on its regulation of macrophage inflammation. Transcriptomic profiling and functional validation in bone marrow-derived macrophages suggested GPR35 as a potential target of mesaconate. Further mechanistic studies revealed that mesaconate alleviates macrophage ferroptosis via GPR35, thereby contributing to its anti-inflammatory effects. In a myocardial ischemia/reperfusion model, mesaconate significantly attenuated cardiac injury, improved systolic function, and reduced infarct size, while myeloid-specific GPR35 knockdown abolished these protective effects. In aged mice, mesaconate ameliorated cardiac hypertrophy and vascular dysfunction, effects closely associated with suppressed macrophage inflammation. Collectively, this study demonstrates for the first time that mesaconate alleviates macrophage inflammation by activating GPR35 to suppress ferroptosis, confers GPR35-dependent cardioprotection in ischemic injury, and mitigates aging-related cardiovascular pathology, highlighting mesaconate as a promising therapeutic candidate for inflammatory cardiovascular diseases.
