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
Pathological cardiac hypertrophy is an independent risk factor for complications such as arrhythmia, myocardial infarction, sudden mortality and heart failure. Succinate, an intermediate product of the Krebs cycle, is released into the bloodstream by cells; its levels increase with exacerbations of hypertension, myocardial and other tissue damage and metabolic disease. Succinate may also be involved in several metabolic pathways and mediates numerous pathological effects through its receptor, succinate receptor 1 (SUCNR1; previously known as GPR91). Succinate-induced activation of SUCNR1 has been reported to be related to cardiac hypertrophy, making SUCNR1 a potential target for treating cardiac hypertrophy. Traditional Chinese medicine (TCM) and its active ingredients have served important roles in improving cardiac functions and treating heart failure. The present study investigated whether 4'-O-methylbavachadone (MeBavaC), an active ingredient of the herbal remedy Fructus Psoraleae, which is often used in TCM and has protective effect on myocardial injury and hypertrophy induced by adriamycin, ischemia-reperfusion and sepsis, could ameliorate succinate-induced cardiomyocyte hypertrophy by inhibiting the NFATc4 pathway. Using immunofluorescence staining, reverse transcription-quantitative PCR, western blotting and molecular docking analysis, it was determined that succinate activated the calcineurin/NFATc4 and ERK1/2 pathways to promote cardiomyocyte hypertrophy. MeBavaC inhibited cardiomyocyte hypertrophy, nuclear translocation of NFATc4 and ERK1/2 signaling activation in succinate-induced cardiomyocytes. Molecular docking analysis revealed that MeBavaC interacts with SUCNR1 to form a relatively stable binding and inhibits the succinate-SUCNR1 interaction. The results demonstrated that MeBavaC suppressed cardiomyocyte hypertrophy by blocking SUCNR1 receptor activity and inhibiting NFATc4 and ERK1/2 signaling, which will contribute to the preclinical development of this compound.
