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
Objective: This study aims to investigate the potential of electroacupuncture to mitigate myocardial ischemia-reperfusion injury (MIRI) by influencing N6-methyladenosine (m6A) methylation through modulation of the fat mass and obesity-associated protein (FTO). Methods: An experimental murine model of MIRI was established by surgically occluding the left anterior descending coronary artery, followed by reperfusion. Electroacupuncture treatment targeting Neiguan acupoints was administered 7 days before ischemia induction. Cardiac function was evaluated using echocardiography, and myocardial infarction size was assessed through Evans Blue and triphenyltetrazolium chloride dual staining. To measure m6A methylation and mRNA expression of FTO and mediator complex subunit 1 (Med1), RNA immunoprecipitation and quantitative polymerase chain reaction were utilized. Western blot analysis was conducted to determine the protein expression levels of Med1, Bcl-2, and Bax. Results: Electroacupuncture pretreatment was associated with a reduction in myocardial injury, demonstrated by preserved ejection fraction and reduced infarct size. Enhanced FTO expression and decreased m6A methylation were observed in myocardial tissue following electroacupuncture treatment. Additionally, Med1 - a downstream target of m6A - exhibited decreased mRNA expression in the electroacupuncture-treated group, correlating with reduced cardiomyocyte apoptosis. Conclusion: Electroacupuncture pretreatment may confer cardioprotective effects in MIRI by upregulating FTO, thereby modulating m6A methylation and reducing Med1 expression.
