The Effect of Gastric Bypass with a Distal Gastric Pouch on Glucose Tolerance and Diabetes Remission in Type 2 Diabetes Sprague-Dawley Rat Model.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundGastric bypass with a proximal gastric pouch (Roux-en-Y gastric bypass) induces early diabetes remission. The effect of gastric bypass with a distal gastric pouch remains unknown.
objectiveTo observe the effect on glucose tolerance and diabetes remission of gastric bypass with a distal gastric pouch.
methodA type 2 diabetes (T2D) model was created in 44 Sprague-Dawley (SD) rats that randomly underwent Roux-en-Y gastric bypass (RYGB, n = 8); gastric bypass with duodenal-jejunal transit (GB-DJT, n = 8); distal-pouch gastric bypass with duodenal-jejunal transit (DPGB-DJT, n = 8); distal-pouch gastric bypass with duodenal-jejunal bypass (DPGB-DJB, n = 8); sham (n = 6); and Roux-en-Y gastric bypass with esophageal re-anastomosis (RYGB-Er, n = 6) surgery. In the DPGB-DJT and the DPGB-DJB groups, the gastric pouch was created in the distal stomach. In the RYGB and the GB-DJT groups, the gastric pouch was created in the proximal stomach. An oral glucose tolerance test (OGTT), insulin tolerance test (ITT) and mixed-meal tolerance test (MMTT) conducted preoperatively were repeated postoperatively.
resultsGLP-1 AUC recorded preoperatively was significantly increased 8 weeks postoperatively in the RYGB, GB-DJT, and DPGB-DJB groups. Increased GLP-1 AUC in the DPGB-DJT did not reach statistical significance. Improved glucose tolerance in the RYGB and GB-DJT groups was significantly higher than DPGB-DJT group. DPGB-DJB did not improve glucose tolerance significantly. Gastrin level was increased significantly in the DPGB-DJT and DPGB-DJB groups.
conclusionIn gastric bypass, creating the gastric pouch in the distal region of the stomach significantly impairs the glucose tolerance and diabetes remission in spite of the increased GLP-1 and insulin responses in T2D SD rat model, suggesting that bypassing the distal stomach may be the key mediator of early diabetes remission after RYGB.
