The post-prandial pattern of gut hormones is related to magnitude of weight-loss following gastric bypass surgery: a case-control study.
Article in Scandinavian journal of clinical and laboratory investigation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03341429 (BARI-OPTIMISE), which is not on this map. Cited by 6 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.

Abstract
backgroundThe mechanisms of weight loss after gastric bypass, including the role of gastric hormones, are still not completely understood. While postprandial releases of peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) increase post-surgery and ghrelin usually is reduced, their relationship to the magnitude of the weight loss is still obscure. We explored if differing weight loss after Roux Y gastric bypass (RYGB) in morbidly obese were associated with differing postprandial hormonal release.
methodsWe compared patients with large (> 40%) or moderate (< 25%) weight loss three years following RYGP surgery, and an obese control group scheduled for RYGB (six in each group). A 300 kcal mixed meal test was given with blood sampling before and thereafter at 30-min intervals in 180 min. Peak and incremental area under the curve (iAUC) were calculated to characterize postprandial responses.
resultsEarly postprandial GLP-1 response were significantly higher in the RYGB groups than in the controls, and highest in those with largest weight loss. Postprandial PYY response were also greater for the two RYGB groups vs. controls, but interestingly the controls had higher baseline values. Ghrelin, from similar baseline, was only suppressed in those with the largest weight loss, with close to no reduction in those with modest weight loss or controls.
conclusionsThese results support the hypothesis that the magnitude of weight loss after RYGB surgery might be associated with differing patterns of postprandial responses in GLP-1 and ghrelin, but not PYY. Larger studies are warranted.
