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
Introduction: Primary biliary cholangitis (PBC) is a chronic autoimmune-mediated cholestatic liver disease that can progress to cirrhosis and liver failure. Intrahepatic biliary epithelial cells (IBECs) are the primary targets of early injury in PBC. Our previous studies have shown that exosomes derived from hepatic stellate cells (HSCs) deliver miR-122-5p to regulate the expression of human IBEC inflammatory factors via the p38 MAPK signaling pathway. The purpose of this study was to investigate the therapeutic potential and molecular mechanism of HSC-derived exosomal miR-122-5p in PBC. Methods: The effects of exosomal miR-122-5p in inhibiting apoptosis, epithelial-mesenchymal transition (EMT), and fibrosis were evaluated in lipopolysaccharide (LPS)-induced human IBEC models, and its anti-inflammatory and anti-fibrotic effects were measured in dnTGF-βRII mouse models. A variety of analytical procedures, such as flow cytometry, Cell Counting Kit-8 (CCK-8), RT-qPCR, ELISA, co-culture, Western blotting, immunofluorescence, gene transfection, immunohistochemistry, and several staining methods (H&E and Masson), were used to evaluate the effectiveness and mechanisms of these methods. Results: The results from clinical data showed that exosomal miR-122-5p was correlated with liver function, and when combined with gp210 and sp100 antibodies, it could improve the sensitivity of PBC diagnosis. The results from Conclusion: In conclusion, exosomal miR-122-5p alleviates liver pathology in PBC by targeting the TNFRSF19/ASK1/p38 MAPK axis, highlighting its potential as both a diagnostic biomarker and a therapeutic target for PBC.
