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
objectiveTo explore the role of extranuclear p53-mediated autophagy suppression by regulating AMPK/mTOR signaling pathway in heat stress (HS)-induced injury of mouse aortic endothelial cells (MAECs).
methodsPrimary cultures of MAECs were pretreated with compound C (an AMPK inhibitor), rapamycin (a mTOR inhibitor) or pifithrin-α (PFT, a selective p53 inhibitor) for 1 h before exposure to HS (43 ℃) for 2 h. The changes in cell viability at different time points after HS were examined using CCK-8 assay, and the protein expressions of P53, LC3-II, Beclin-1, p62 and the AMPK/mTOR signaling proteins were detected using Western blotting. In the animal experiment, C57 mice were pretreated with compound C, rapamycin or PFT and exposed to a high temperature at 40 ℃ to induce HS. The pathological changes in the aorta of the mice were observed with HE staining, and cell apoptosis was detected using TUNEL staining.
resultsIn cultured MAECs, the cell viability was significantly reduced (
conclusionAutophagy inhibition mediated by extranuclear p53
