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
objectivesTo investigate the mechanism of poricoic acid A (PAA) for alleviating dextran sulfate sodium (DSS)-induced colitis in mice.
methodsEighteen C57BL/6 mice were randomly divided into control group, DSS-induced colitis model group, and PAA intervention (10 mg/kg) group. The changes in body weight, colon length, disease activity index (DAI), and histopathological scores of the mice were evaluated. In a DSS-induced Caco-2 cell model, the changes in expressions of ZO-1, claudin-1, Bcl-2, Bax, cleaved caspase-3, LC3-II/I, and P62 were detected. Molecular docking and Western blotting were used to analyze the mechanisms underlying the ameliorating effect of PAA on DSS-induced colitis.
resultsIn the mouse models of DSS-induced colitis, PAA significantly ameliorated DSS-induced weight loss, colon shortening, and elevation of DAI scores while reducing colonic IL-1β and TNF-α levels. HE staining showed that PAA obviously alleviated colonic crypt damage, reduced inflammatory cell infiltration, and lowered histopathological scores of the colon. AB-PAS staining revealed significantly increased goblet cell counts in PAA-treated mice compared to those in DSS group. In DSS-induced Caco-2 cells, PAA treatment effectively inhibited DSS-induced downregulation of the tight junction proteins, reduced Bax and cleaved caspase-3 expressions, increased Bcl-2 expression and the LC3-II/I ratio, and decreased P62 expression. Mechanistic study suggested that PAA targeted the AMPK/mTOR pathway to activate autophagy and suppress cell apoptosis.
conclusionsPAA protects intestinal barrier function and alleviates DSS-induced colitis in mice by activating AMPK/mTOR-mediated autophagy and inhibiting intestinal epithelial cell apoptosis.
