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) modifies various aspects of eating behavior in morbidly obese individuals to cause marked and lasting weight loss and improvements in metabolic health, but the underlying mechanisms remain poorly understood.

objectivesTo assess the relative contributions of the gut hormones glucagon-like peptide 1 (GLP-1) and peptide tyrosine tyrosine 3-36 (PYY

settingUniversity hospital, Würzburg, Germany.

methodsHF diet-induced obese male Wistar rats underwent RYGB (n = 11) or sham (n = 7) surgeries and were subsequently maintained on a choice of low-fat (10% calories from fat) and HF (60% calories from fat) diets. From postoperative weeks 4 to 6, acute feeding studies were performed in which the selective GLP-1 receptor antagonist exendin-9 (30 μg/kg), the second-generation selective Y2 receptor antagonist JNJ-31020028 (10 mg/kg), or a combination of both drugs was administered intraperitoneally.

resultsDuring the observational period weight, adiposity and total food intake were lower while postprandial plasma GLP-1 and peptide tyrosine tyrosine levels were higher for RYGB-operated compared with sham-operated rats. There was a gradual shift in preference from HF to low-fat food in RYGB-operated rats by postoperative week 3. Single antagonist treatments had a relatively modest impact on HF food preference in rats from both surgical groups. However, dual antagonist treatment caused a striking increase in HF food preference specifically in RYGB-operated rats.

conclusionsGLP-1 and peptide tyrosine tyrosine 3-36 reduce HF food preference additively after RYGB supporting the use of gut hormone combination strategies for healthier feeding behavior.
