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
Background: Cholestasis is challenging to treat due to lacked effective drugs. N-(3,4,5-trichlorophenyl)-2 (3-nitrobenzenesulfonamido) benzamide, abbreviated as IMB16-4, which may be effective for the treatment of cholestasis. However, its poor solubility and bioavailability seriously obstruct the research programs. Methods: A hot-melt extrusion (HME) preparation was first applied to increase the bioavailability of IMB16-4, the oral bioavailability, anti-cholestatic effect and vitro cytotoxicity of IMB16-4 and IMB16-4-HME were evaluated. Meanwhile, the molecular docking and qRT-PCR were used to validate the mechanism behind. Results: The oral bioavailability of IMB16-4-HME improved 65-fold compared with that of pure IMB16-4. Pharmacodynamics results demonstrated that IMB16-4-HME prominently decreased the serum levels of total bile acid (TBA) and alkaline phosphatase (ALP), but elevated the level of total bilirubin (TBIL) and direct bilirubin (DBIL). Histopathology revealed that IMB16-4-HME at lower dose exhibited stronger anti-cholestatic effect compared with pure IMB16-4. In addition, molecular docking demonstrated that IMB16-4 has great affinity with PPARα, and qRT-PCR results revealed that IMB16-4-HME significantly elevated the mRNA expression level of PPARα, but decreased the mRNA level of CYP7A1. Cytotoxicity assays demonstrated that the hepatotoxicity of IMB16-4-HME was absolutely attributed to IMB16-4, and the excipients of IMB16-4-HME may increase the drug load within HepG2 cells. Conclusion: The HME preparation significantly increased the oral bioavailability and anti-cholestatic effect of pure IMB16-4, but caused liver injury at high dose, which require a dose balance between the curative effect and safety in the future research.
