How does patient reported satiety, hunger, and appetite change after metabolic and bariatric surgery? A comparison between sleeve gastrectomy and Roux-en-Y gastric bypass.
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSatiety, cravings, and appetite have a behavioral impact on eating and may be associated with obesity. There are limited data evaluating the trajectory of hunger after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).
methodsMetabolic and bariatric surgery (MBS) patients were given the Daily Eats questionnaire at their preoperative and postoperative appointments. Daily Eats is a validated survey which asks patients to rate hunger, appetite, cravings, and satiety on a scale of 0-10. Cross-sectional data were obtained at five timepoints including preoperative visits and postoperative appointments at monthly intervals including: 0-12, 12-24, 24-36, and > 36. Average Daily Eats scores in the postoperative setting for SG and RYGB patients were compared using independent sample t-tests with a p-value of < 0.05 indicating significance.
resultsThere were 3898 Daily Eats questionnaires completed (2334 preoperative, 996 postoperative SG, 568 postoperative RYGB). Patient-reported outcome measures (PROMs) survey compliance was 77% at the time of this study with 2334/2537 (92%) preoperative surveys completed and 1564/2523 (62%) postoperative surveys completed. Patients who underwent SG reported significantly higher scores for hunger (4.87 ± 2.33 vs. 3.53 ± 2.16; p < 0.01) and appetite (5.07 ± 2.05 vs. 3.85 ± 1.76; p < 0.01) at 24-36 months when compared to patients who underwent RYGB. Patients who were > 36 months after SG reported significantly higher scores for hunger (4.58 ± 2.21 vs. 3.94 ± 2.39; p < 0.01) and appetite (4.67 ± 1.90 vs. 4.08 ± 2.27; p < 0.01) when compared to patients who underwent RYGB.
conclusionCompared to RYGB, patients who underwent SG reported significantly more long-term hunger and appetite. PROMs after MBS may enable tailored postoperative care by procedure and improve preoperative counseling by illustrating how hunger-related sensations evolve differently depending on the surgical procedure.
