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
objectiveThe cannabinoid receptor-2 agonist AM1241 exhibits notable cardioprotective effects against myocardial infarction, positioning it as a promising therapeutic candidate for cardiovascular disease. This study explores AM1241's protective role in myocardial ischemia-reperfusion (IR) injury and its association with the Nrf2/HO-1 pathway.
methodsIn an established Sprague-Dawley rat IR model, AM1241's impact on cardiac injury was assessed through echocardiography, 2,3,5-triphenyl tetrazolium chloride staining, and histological analysis. H9c2 cells underwent hypoxia-reoxygenation, with AM1241's influence on cell viability determined by the CCK-8 assay. Reactive oxygen species (ROS) production was measured using the DCFH-DA assay, and Nrf2 and HO-1 protein expressions were evaluated through immunofluorescence and Western blot.
resultsMyocardial ischemia-reperfusion injury (MIRI) increased infarct size, inflammatory cell presence, oxidative and nitrosative stress, impaired cardiac function, and elevated apoptosis rates. AM1241 mitigated these effects, enhancing cell viability, reducing ROS production, and upregulating Nrf2 and HO-1 expression. The antioxidant effect of AM1241 was inhibited by ML385 intervention.
conclusionsAM1241 attenuates oxidative stress, alleviates MIRI, and activates the Nrf2/HO-1 signaling pathway, underscoring its potential as a therapeutic strategy for MIRI.
