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

backgroundGallstone disease (GD) has been associated with low serum levels of plant sterols. We evaluated the impact of laparoscopic Roux-en-Y gastric bypass (LRYGB) and non-alcoholic fatty liver disease (NAFLD) on the association of GD with low levels of serum plant sterols.

methodsTwo hundred forty-two consecutive morbidly obese patients were recruited to this prospective study. Histological analysis of liver biopsy to diagnose NAFLD was performed. Bile sample was taken during the LRYGB. Associations of GD with serum non-cholesterol sterol to cholesterol ratios, measured using gas liquid chromatography and with mRNA expression of genes participating in the cholesterol, bile, and fatty acid metabolism in the liver, were analyzed.

resultsOut of the 242 participants, 95 had GD. Lower weight (p = 0.002) and female sex (p = 0.0006) were associated with GD. Serum plant sterols, campesterol (p = 0.003), sitosterol (p = 0.002), and avenasterol (p = 0.015), were lower in patients with GD compared to those without GD. This association remained significant after adjustment for NAFLD, use of statin medication, and previous laparoscopic cholecystectomy (LCC). Levels of sitosterol (p = 0.001) and campesterol (p = 0.001) remained lower in obese individuals with GD also after obesity surgery. Liver mRNA expression of genes regulating cholesterol synthesis and bile metabolism was increased in individuals with GD.

conclusionsSerum plant sterols were lower in patients with GD independent of NAFLD, history of LCC, use of statin medication, and weight loss after LRYGB. Low serum plant sterols in patients with GD suggest potentially inherited alterations in sterol absorption and biliary transport in subjects susceptible for GD.
