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
backgroundIA-0130 is a derivative of 3-(1,3-diarylallylidene)oxindoles, which is a selective estrogen receptor modulator (SERM). A previous study demonstrated that SERM exhibits anti-inflammatory effects on colitis by promoting the anti-inflammatory phenotype of monocytes in murine colitis. However, the therapeutic effects of oxindole on colitis remain unknown. Therefore, we evaluated the efficacy of IA-0130 on dextran sulfate sodium (DSS)-induced mouse colitis.
methodsThe DSS-induced colitis mouse model was established by administration of 2.5% DSS for 5 days. Mice were orally administered with IA-0130 (0.01 mg/kg or 0.1 mg/kg) or cyclosporin A (CsA; 30 mg/kg). Body weight, disease activity index score and colon length of mice were calculated and histological features of mouse colonic tissues were analyzed using hematoxylin and eosin staining. The expression of inflammatory cytokines and tight junction (TJ) proteins were analyzed using quantitative real-time PCR and enzyme-linked immunosorbent assay. The expression of interleukin-6 (IL-6) signaling molecules in colonic tissues were investigated using Western blotting and immunohistochemistry (IHC).
resultsIA-0130 (0.1 mg/kg) and CsA (30 mg/kg) prevented colitis symptom, including weight loss, bleeding, colon shortening, and expression of pro-inflammatory cytokines in colon tissues. IA-0130 treatment regulated the mouse intestinal barrier permeability and inhibited abnormal TJ protein expression. IA-0130 down-regulated IL-6 expression and prevented the phosphorylation of signaling molecules in colonic tissues.
conclusionsThis study demonstrated that IA-0130 suppressed colitis progression by inhibiting the gp130 signaling pathway and expression of pro-inflammatory cytokines, and maintaining TJ integrity.
