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
MicroRNA (miR)-21-5p is a newly discovered factor that mediates TGF-β1 signaling. The present study was designed to investigate the role of TGF-β1/miR-21-5p in hepatitis B virus (HBV)-induced liver fibrosis. HBV-infected sodium taurocholate co-transporting polypeptide (NTCP)-transfected Huh7.5.1 cells were co-cultured with LX2 cells to simulate HBV infection in the present study. A total of 29 patients with chronic HBV infection were enrolled. Cells were transfected with miR-21-5p mimic or inhibitor with or without TGF-β1 stimulation. The demographic, biochemical and virological data from the 29 patients were analyzed and liver tissues were collected. miR-21-5p levels and the mRNA and protein expression of α-smooth muscle actin (SMA), collagen type 1 α 1 (CoL1A1), tissue inhibitor of metalloproteinase (TIMP)-1 and Smad from liver cells or tissues were detected by quantitative PCR analysis and western blotting, respectively. Cell viability was observed, and the liver fibrosis score was evaluated. The association between miR-21-5p and liver fibrosis was evaluated by correlation analysis. HBV infection upregulated TGF-β1/miR-21-5p mRNA expression in NTCP-Huh7.5.1 cells compared with mock infection (P<0.05). TGF-β1 incubation significantly increased miR-21-5p levels, as well as the mRNA and protein expression of α-SMA, CoL1A1 and TIMP-1, and reduced Smad7 expression in LX2 cells compared with the normal group, and these effects were counteracted by miR-21-5p inhibitor (P<0.05). miR-21-5p overexpression also contributed to TGF-β1-induced α-SMA, CoL1A1 and TIMP-1 expression in LX2 cells (P<0.05). Co-culture with HBV-infected NTCP-Huh7.5.1 cells upregulated TGF-β1/miR-21-5p activity and CoL1A1 expression in LX2 cells compared with normal control, which were significantly reduced by miR-21-5p inhibitor (P<0.05). miR-21-5p levels were significantly correlated with the liver fibrosis score (r=0.888; P<0.05). These data demonstrated that HBV induced liver fibrosis via the TGF-β1/miR-21-5p pathway and suggested that miR-21-5p may be an effective anti-fibrosis target.
