Cholesterol metabolism in acute upper gastrointestinal bleeding, preliminary observations.
Article in Wiener klinische Wochenschrift, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Hypocholesterolemia is commonly found in critically ill patients; however, the aetiology of this condition remains unclear. Several clinical studies refer to the possible negative impact of haemodilution on cholesterol (CH) metabolism in acute medical conditions. The aim of this study was to examine the serum CH profile (total CH, LDL and HDL CH) during acute gastrointestinal bleeding which is a life-threatening condition characterised by alterations in lipid metabolism. Serum non-CH sterols (lathosterol, squalene, sitosterol and campesterol) concentrations as markers of CH synthesis and CH absorption were measured at the same time. Twenty-four patients with acute upper gastrointestinal bleeding (UGIB) were measured for these parameters over a 6-day period. The control group was 100 healthy blood donors.We found lower plasma levels of total CH (p < 0.001) and LDL CH (p < 0.05) in patients with UGIB than in the control group. The decreased HDL CH plasma levels in patients were not statistically significant. In addition, patients had significantly lower plasma levels of lathosterol, squalene, campesterol and sitosterol (p < 0.05).Our results showed abnormalities not only in the CH plasma profile, but also in plasma concentrations of non-CH sterols. These findings of alterations in both the CH synthesis and absorption process could be a contributory cause of hypocholesterolemia during acute gastrointestinal bleeding. However, further research is necessary.
