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 investigate the efficacy and mechanism of Qifu Lizhong enema prescription(, QFLZ) on intervening ulcerative colitis (UC) rat model with TCM spleen and kidney insufficiency syndrome.
methodsSeventy-two male Sprague-Dawley rats were randomly assigned to six groups: normal model, mesalazine, and QFLZ high, medium, and low dose groups, each with 12 rats. After 3 d of adaptation feeding, all groups except the normal group were induced using rhubarb decoction in combination with trinitrobenzene sulfonic acid (TNBS)/55 % ethanol to establish a UC rat model. Following successful modeling, the normal and model groups received daily saline enema, while the Chinese medicine and Western medicine groups received daily QFLZ and Mesalazine enema for 2 weeks respectively. The disease activity index score, hematoxylin and eosin staining, immunohistochemistry, and Western blotting were used to determine the expression of claudin 1, claudin 2, zonula occludens-1 protein (ZO-1), and F-actin proteins in each rat colon tissue following treatment.
resultsQFLZ significantly alleviated the structural disorganization in the form of epithelial glands in the intestinal mucosa of rats with UC and retarded the progression of the disease. The intestinal mucosal epithelial cells of UC rats showed decreased expression of claudin 1, ZO-1, F-actin ( 0.05), claudin 2 appeared elevated ( 0.05), which resulted in impaired TJ. Treatment with QFLZ resulted in elevated expression of claudin 1 ( 0.05), ZO-1 ( 0.05) and F-actin ( 0.05) and decreased expression of claudin 2 ( 0.05), which allowed for repair of the intestinal mucosal TJ, which in turn served as a treatment for UC.
conclusionsThe mechanism of repairing TJ function and repairing the intestinal mucosal barrier by QFLZ may be associated with up-regulation of claudin 1, ZO-1, and F-actin levels, and down-regulation of claudin 2 expression level.
