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

BACKGROUND/

objectivesAs a proinflammatory cytokine, interleukin-17 (IL-17) contributes to the inflammation of many autoimmune diseases. We examined IL-17 levels in serum and tissues from patients with chronic hepatitis B virus infection (HBV), and especially evaluated the role of IL-17 in the pathogenesis and progression of liver fibrosis. MATERIALS AND

methodsWhole venous blood was obtained from four patient groups: chronic hepatitis B (CHB, n = 47), liver cirrhosis (LC, n = 49), primary hepatocellular carcinoma (PHC, n = 44), chronic liver failure (CLF, n = 33), and a normal control group (n = 20). HBsAg was positive in all patients. Liver biopsy samples were acquired from asymptomatic HBsAg carriers (ASC, n = 35), CHB (n = 57), and LC (n = 31) patients. We performed ELISA to measure IL-17 levels in serum samples, and used reverse RT-PCR to measure IL-17 mRNA levels in peripheral blood mononuclear cells (PBMC). IL-17 protein expression was detected in liver biopsy tissues by immunohistochemistry.

resultsCompared to normal controls, serum IL-17 protein and mRNA levels were significantly higher in the four infection groups. LC patients exhibited the highest serum IL-17 and PBMC mRNA levels. No significant differences were found between the other three groups. High levels of IL-17 were also observed in tissues from CHB and LC patients, compared to ASC. IL-17 expression was mainly located in the portal area and was positively correlated with inflammation grade and fibrosis stage.

conclusionsIL-17 expression was found to be increased with increasing degrees of liver fibrosis. This suggests that IL-17 may not only induce the inflammation, but also contribute to disease progression and chronicity.
