1 · What the graph read from it

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.

2 · The registry

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

Treatment of chronic hepatitis C virus with direct-acting antivirals usually eradicates infection, but liver fibrosis does not resolve concurrently. In patients who develop cirrhosis prior to hepatitis C virus treatment, hepatic decompensation and hepatocellular carcinoma can still occur after viral elimination due to residual fibrosis. We hypothesized the liver proteome would exhibit meaningful changes in inflammatory and fibrinogenic pathways change upon hepatitis C virus eradication, which could impact subsequent fibrosis regression. We analysed the liver proteome and phosphoproteome of paired liver biopsies obtained from 8 hepatitis C virus-infected patients before or immediately after treatment with direct-acting antivirals. Proteins in interferon signalling and antiviral pathways decreased concurrent with hepatitis C virus treatment, consistent with prior transcriptomic analyses. Expression of extracellular matrix proteins associated with liver fibrosis did not change with treatment, but the phosphorylation pattern of proteins present within signalling pathways implicated in hepatic fibrinogenesis, including the ERK1/2 pathway, was altered concurrent with hepatitis C virus treatment. Hepatitis C virus treatment leads to reduced expression of hepatic proteins involved in interferon and antiviral signalling. Additionally, changes in fibrosis signalling pathways are detectable before alteration in extracellular matrix proteins, identifying a putative chronology for the dynamic processes involved in fibrosis reversal.
