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
purposeDoxorubicin (DOX) is a broad-spectrum anti-tumor anthracycline drug. However, its clinical application is greatly limited due to the side effect of cardiotoxicity. Caffeic acid phenethyl ester (CAPE) is one of the major biologically active compounds isolated from propolis, which is effective in the treatment of cardiovascular diseases. The purpose of this study aimed to explore the possible mechanism of CAPE's protective effect on DOX-induced cardiotoxicity (DIC).
methodsIn vivo, a DIC model was established by the intraperitoneal injection of 3 mg/kg DOX. The cardiac function of mice was monitored by electrocardiograms. Histopathological changes in myocardial tissue were detected by H&E staining. Serum samples were tested for the level of markers of myocardial injury. In vitro, transmission electron microscopy was used to assess the mitochondrial damage. Oxidative stress was measured by flow cytometry and mitochondrial respiration analysis. Necroptosis pathway changes were detected by Western blotting. Furthermore, the overexpression plasmid of a key necroptosis gene, necroptosis inhibitor or ROS inducer/inhibitor was applied to H9c2 and AC16 cells to explore whether CAPE exerted a protective effect against DIC through the cross-talk mediated by ROS and MLKL.
resultsCAPE could improve the cardiac function and protect against myocardial tissue. CAPE pre-administration treatment attenuated the DOX-induced generation of ROS, protected mitochondrial functions and inhibited necroptosis. Moreover, there was cross-talk between the ROS and necroptosis. CAPE could protect against DIC by inhibiting the ROS-MLKL signaling that regulated the cross-talk.
conclusionsCAPE alleviated the oxidative stress and necroptosis of DIC, indicating that the cross-talk mediated by ROS-MLKL signaling may be a potential therapeutic mechanism for clinical DIC.
