Effect of glucocorticoid pretreatment on oxidative liver injury and survival in jaundiced rats with endotoxin cholangitis.
Article in World journal of surgery, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionBiliary tract infection is associated with high mortality. This study investigated the effect of glucocorticoid pretreatment on lipopolysaccharide (LPS)-induced cholangitis.
methodsRats undergoing either sham operation or ligation of the extrahepatic bile duct (BDL) for 2 weeks were randomly assigned to receive intravenous injections of dexamethasone (DX) or normal saline (NS) prior to infusing LPS into the biliary tract. The plasma levels of tumor necrosis factor-alpha (TNFalpha), chemokines monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-2 (MIP-2) as well as liver mRNA expression of MCP-1 and MIP-2 were determined. Infiltration of monocytes, Kupffer cells, and neutrophils in rat liver were studied with immunohistochemistry. Oxidative liver injury was measured by the malondialdehyde (MDA) content.
resultsDexamethasone pretreatment resulted in significantly decreased plasma levels of TNFalpha at 1 hour, MCP-1 and MIP-2 at 2 and 3 hours, and decreased liver MCP-1 mRNA expression at 3 hours following LPS infusion in BDL-DX rats than in BDL-NS rats. The number of inflammatory cells in the liver was significantly different between sham- and BDL-treated rats but was not affected by DX pretreatment. Pretreatment with DX resulted in significantly decreased liver MDA contents in the BDL-DX group than that in the BDL-NS group. Jaundiced rats pretreated with 5 mg DX prior to infusion of 1 g of LPS were 6.8 times more likely to survive than those that were not pretreated.
conclusionsPretreatment of jaundiced, LPS-treated rats with a supraphysiological dose of dexamethasone may rescue their lives by suppression of chemokine expression and alleviation of oxidative liver injury.
