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
The proposed objective of this study is to attenuate cardiac fibrosis by inhibiting NLRP3 inflammasome and related genes in uninephrectomized-DOCA fed rat model. Cardiac fibrosis was induced in male Sprague Dawley rats by uninephrectomy and by subsequent administration of deoxycorticosterone acetate (DOCA) every 4th day till 28 days along with 1% NaCl in drinking water. Further, the animals in treatment groups were treated with Glibenclamide (10, 20 and 40 mg/kg) for 28 days which was selected based on docking study. Interim analysis was carried out on the 14th day to assess the hemodynamic parameters. On the 28th day, anthropometric, hemodynamic, biochemical and oxidative stress parameters, gene expression (TGF-β1, pSmad 2/3, NLRP3, IL-1β and MMP-9), ex vivo Langendorff studies and Masson's trichrome staining of heart was carried out. Results were interpreted using ANOVA followed by post hoc Bonferroni test. Glibenclamide treatment significantly reduced the increase in blood pressure. Furthermore, the ECG patterns of the treatment groups displayed a lower frequency of the slow repolarizing events seen in the model animals. Moreover, Glibenclamide treatment demonstrated normal LV function as evidenced by a significant decrease in LVEDP. Besides, this intervention improved the anthropometric parameters and less collagen deposition in Masson's trichrome staining. The cascade of TGF-β1-pSmad2/3-NLRP3 was downregulated along with suppression of IL-1β. Our study repositioned anti-diabetic drug Glibenclamide to treat cardiac fibrosis by inhibiting the TGF-β1-pSmad2/3-NLRP3 cascade.
