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 differentiation of mesenchymal stem cells (MSCs) into hepatocyte-like cells (HLCs) is considered one of the most promising strategies for alternative hepatocyte transplantation to treat end-stage liver disease. To advance this method, it is crucial to gain a deeper understanding of the mechanisms governing hepatogenic differentiation. The study demonstrated that suppression of the intracellular domain release of the Notch pathway receptor via the γ-secretase inhibitor N-[(3, 5-difluorophenyl)acetyl]-L-alanyl-2-phenylglycine-1, 1-dimethylethyl ester (DAPT) significantly promotes the expression of hepatocyte-related genes and proteins in HLCs. Increased expression of intracellular inducible NO synthase (iNOS) during differentiation led to elevated endogenous NO production. Biotin switch assays revealed a gradual increase in S-nitrosylation (SNO)-NOTCH1 and a decrease in overall NOTCH1 expression during hepatogenic differentiation. The addition of the exogenous NO donor S-nitrosoglutathione (GSNO) and the SNO inhibitor dithiothreitol (DTT) further demonstrated that the elevated expression of SNO-NOTCH1 promotes the differentiation of MSCs into mature hepatocytes. Briefly, our results fully demonstrated that the modification of the extracellular domain of NOTCH1 by NO, leading to the formation of SNO-NOTCH1, significantly promotes hepatogenic differentiation by inhibiting the Notch signalling pathway. Our study highlights the critical role of SNO-NOTCH1 in regulating the Notch signalling pathway and offers new insights into the mechanisms driving this differentiation process.
