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

In an effort to understand the role of IL-6/gp130 signaling in chronic liver injury, IL-6 deficient (IL-6(-/-)) and wild-type control (IL-6(+/+)) mice were subjected to bile duct ligation (BDL) for 12 weeks. This maneuver causes chronic biomechanical stress and liver injury, fueling sustained biliary epithelial and hepatocyte proliferation. By 12 weeks after BDL, IL-6(-/-) mice develop significantly higher total serum bilirubin levels (23.2 +/- 2.3 versus 14.9 +/- 2.1 mg/dl, P < 0.0001; delta bilirubin subfraction 16.7 +/- 4.0% versus 9.2 +/- 1.8%; P < 0.002), and the majority (15/18) show "black" gallbladder bile, compared to IL-6(+/+) mice (5/16; P < 0.003). The IL-6(-/-) mice also cannot sustain the compensatory liver mass increase commonly seen with chronic obstructive cholangiopathy, because of less hepatocyte proliferation, despite a rate of hepatocyte apoptosis similar to that of IL-6(+/+) mice. Moreover, IL-6(-/-) mice show a more advanced stage of biliary fibrosis and a higher mortality rate than the IL-6(+/+) controls (51% versus 23%; P < 0.02). These phenotypic changes in the IL-6(-/-) mice are associated with decreased expression and phosphorylation of gp130 and the transcription factor STAT3, compared to IL-6(+/+) mice. Daily treatment with exogenous recombinant IL-6 for 3-6 weeks starting at 6 weeks after BDL significantly lowers the serum total bilirubin in both groups. In the IL-6(-/-) mice, exogenous IL-6 treatment also increases the level of gp130 protein expression and completely reverses the loss of liver mass by increasing the hepatocyte proliferation. In conclusion, IL-6 appears to contribute to biliary tree integrity and maintenance of hepatocyte mass during chronic injury.
