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
introductionIschemic heart diseases are the leading cause of death worldwide due to the inability of regeneration of adult cardiomyocytes (CMs). Natural products from medical herbs are an important source of innovative drugs for many diseases including cardiovascular diseases.
objectivesIn this study, we set out to screen novel small-molecule therapies from natural products to protect heart against ischemic injury.
methodsHigh-throughput screening was performed using a natural product library to identify the potential small molecules which can promote survival of CMs under ischemic and ischemic/reperfusion conditions. In addition, myocardial infarction (MI) and ischemia/reperfusion (I/R) mice models were used to evaluate the in vivo effects of the screened candidate. We also applied various analysis including cell viability, qPCR, Western blot, immunofluorescent staining, echocardiography, Masson's staining, TTC staining, and network pharmacology.
resultsHigh-throughput screening showed that the small molecule compound Darutigenol (Dar), derived from the Chinese traditional herb Herba Siegesbeckiae, could significantly promote CM survival and proliferation under ischemic conditions. Moreover, I/R-induced CM apoptosis and ROS generation could be significantly reduced by Dar treatment. In addition, in vivo administration of Dar was able to attenuate MI- and I/R-induced cardiac injury in adult mice by decreasing fibrosis and apoptosis, thereby improving cardiac function. Network pharmacology analysis and molecule docking assay showed that Dar has the highest binding affinity with AKT1 protein. Western blotting assay further revealed that AKT1 activation was significantly enhanced by Dar administration in the infarcted hearts.
conclusionsOur data revealed that the small molecule compound Dar, screened from the natural product library in this study, is capable of protecting heart against MI and I/R injury by activating AKT1 pathway. These findings enrich the natural product candidates for cardiovascular disease treatment and provide new insights into potential therapeutic agents for MI and I/R injury.
