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
Bile acids (BAs) play critical physiological functions in cholesterol homeostasis, and deregulation of BA metabolism causes cholestatic liver injury. The long noncoding RNA maternally expressed gene 3 (MEG3) was recently shown as a potential tumor suppressor; however, its basic hepatic function remains elusive. Using RNA pull-down with biotin-labeled sense or anti-sense MEG 3RNA followed by mass spectrometry, we identified RNA-binding protein polypyrimidine tract-binding protein 1 (PTBP1) as a MEG3 interacting protein and validated their interaction by RNA immunoprecipitation (RIP). Bioinformatics analysis revealed putative binding sites for PTBP1 within the coding region (CDS) of small heterodimer partner (SHP), a key repressor of BA biosynthesis. Forced expression of MEG3 in hepatocellular carcinoma cells guided and facilitated PTBP1 binding to the Shp CDS, resulting in Shp mRNA decay. Transient overexpression of MEG3 RNA in vivo in mouse liver caused rapid Shp mRNA degradation and cholestatic liver injury, which was accompanied by the disruption of BA homeostasis, elevation of liver enzymes, as well as dysregulation of BA synthetic enzymes and metabolic genes. Interestingly, RNA sequencing coupled with quantitative PCR (qPCR) revealed a drastic induction of MEG3 RNA in Shp
conclusionMEG3 causes cholestasis by serving as a guide RNA scaffold to recruit PTBP1 to destabilize Shp mRNA. SHP in turn represses CREB-mediated activation of MEG3 expression in a feedback-regulatory fashion. (Hepatology 2017;65:604-615).
