Hepatic stimulator substance alleviates toxin-induced and immune-mediated liver injury and fibrosis in rats.
Article in Digestive diseases and sciences, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLiver fibrosis is a common scarring response to chronic liver injury. It is a precursor to cirrhosis and liver carcinoma. Hepatic stimulator substance (HSS), a known liver-specific but species-nonspecific growth factor, has been shown to protect hepatocytes from various toxins.
methodsWe have investigated the effects of HSS therapy on carbon tetrachloride (CCl(4))-induced and porcine-serum-mediated hepatic injury and fibrosis. We hypothesize that HSS might attenuate liver injury and fibrosis by suppressing oxidative stress, down-regulating profibrogenic factors, and blocking HSCs activation.
resultsThis report demonstrated that HSS therapy diminished α-smooth muscle actin expression, decreased intrahepatic reactive oxygen species (ROS) level, and down-regulated transforming growth factor (TGF)-β1, platelet-derived growth factor (PDGF)-BB, and tissue inhibitor of metalloproteinase (TIMP)-1 expression. In addition, HSS treatment significantly protected the liver from injury by improving liver function tests and histological architecture of the liver.
conclusionsThese results provided novel insights into the mechanisms of HSS in the protection of the liver. Our results suggested that HSS might be a therapeutic antifibrotic agent for the treatment of liver fibrosis.
