Effect of high-fat enteral nutrition on hepatocyte injury in response to hemorrhagic shock in the rat.
Article in World journal of surgery, 2007. 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
backgroundHigh-fat enteral nutrition reduces the inflammatory response following hemorrhagic shock in the rat.
aimsWe hypothesized that this intervention might also ameliorate the remote organ injury to the liver associated with this model.
methodsMale Sprague-Dawley rats were either starved or fed low-fat or high-fat isocaloric isonitrogenous feed prior to nonlethal hemorrhagic shock induced by a 40% reduction in the blood volume. Animals were sacrificed at 90 minutes or 24 hours after injury. Liver cell damage was assessed by histology and long polymerase chain reaction (PCR) to detect mitochondrial DNA damage. Stress protein expression was measured by Western blot and mRNA expression by real-time PCR and immunohistochemistry.
resultsAnimals fed a low-fat diet had the same severity of liver injury as starved animals and increased expression of stress proteins. Animals fed a high-fat diet had minimal liver injury, no evidence of mitochondrial DNA damage, and significantly lower expression of stress proteins. This effect is associated with preservation of hepatocellular morphology, attenuation of mitochondrial DNA damage, and a reduced stress protein response to injury.
conclusionsHigh-fat enteral nutrition protects the liver from the remote effects of hemorrhagic shock, but the mechanism of this effect is not yet known.
