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

backgroundRoux-en-Y gastric bypass (RYGB) is an effective surgical treatment for type 2 diabetes mellitus (T2DM). The present study aimed to investigate the effects of RYGB on glucose homeostasis, lipid metabolism, and liver morphological adaption, as well as the changes in bile acids signaling and expression of its target regulatory factors involved in gluconeogenesis, lipogenesis, and fatty acid β oxidation.

methodsTwenty adult male T2DM rats induced by high-fat diet and a low dose of streptozotocin were randomly divided into sham and RYGB groups. The parameters of body weight, food intake, glucose tolerance, insulin sensitivity, serum lipid profiles, and bile acids level were assessed to evaluate metabolic changes. Liver sections were stained with hematoxylin-eosin (H&E) and oil red O to assess lipid accumulation. The mRNA and protein expression levels of farnesoid X receptor (FXR), small heterodimer partner (SHP), key regulatory factors of gluconeogenesis, lipogenesis, and fatty acid β oxidation (phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (G6Pase), sterol regulatory element-binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor-α (PPAR-α)) were determined through RT-PCR and Western blotting, respectively.

resultsRYGB induced significant improvements in glucose tolerance and insulin sensitivity, along with weight loss and decreased food intake. RYGB also decreased serum TG, FFAs, and increased bile acids levels. The lipid droplets in the liver were significantly decreased after RYGB. The RYGB group exhibited downregulated mRNA and protein expression levels of PEPCK, G6Pase, and SREBP-1c and upregulated expression of FXR, SHP, and PPAR-α in the liver.

conclusionsRYGB ameliorates glucose and lipid metabolism accompanied by weight loss and calorie restriction. The liver exhibited a marked improvement in lipid accumulation after RYGB. The bile acids level, FXR, and its target transcriptional factor SHP expression were elevated. Meanwhile, our study demonstrated that the increased bile acids-FXR signaling, followed by the reduced hepatic gluconeogenesis, lipogenesis, and increased fatty acid β oxidation may contribute to improved metabolic conditions after RYGB.
