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 and Aims: Recognition of excessive activation of hepatic stellate cells (HSCs) in liver fibrosis prompted us to investigate the regulatory mechanisms of HSCs. We aimed to examine the role of O-GlcNAcylation modification of alanine, serine, cysteine transporter 2 (ASCT2) in HSCs and liver fibrosis. Methods: The expression of O-GlcNAcylation modification in fibrotic mice livers and activated HSCs was analyzed by western blotting. Immunoprecipitation was used to assess the interaction of ASCT2 and O-GlcNAc transferase (OGT). In addition, ASCT2 protein stability was assayed after cycloheximide (CHX) treatment. The O-GlcNAcylation site of ASCT2 was predicted and mutated by site-directed mutagenesis. Real-time PCR, immunofluorescence, kit determinations and Seahorse assays were used to clarify the effect of ASCT2 O-GlcNAcylation on HSC glutaminolysis and HSC activation. Western blotting, immunochemistry, and immunohistofluorescence were used to analyze the effect of ASCT2 O-GlcNAcylation Results: We observed significantly increased O-GlcNAcylation modification of ASCT2. ASCT2 was found to interact with OGT to regulate ASCT2 stability. We predicted and confirmed that O-GlcNAcylation of ASCT2 at Thr122 site resulted in HSCs activation. We found Thr122 O-GlcNAcylation of ASCT2 mediated membrane trafficking of glutamine transport and attenuated HSC glutaminolysis. Finally, we validated the expression and function of ASCT2 O-GlcNAcylation after injection of AAV8-ASCT2 shRNA in CCl Conclusions: Thr122 O-GlcNAcylation regulation of ASCT2 resulted in stability and membrane trafficking-mediated glutaminolysis in HSCs and liver fibrosis. Further studies are required to assess its role as a putative therapeutic target.
