Evaluation of patients on immunosuppressants undergoing sleeve gastrectomy, Roux-en-Y gastric bypass, and duodenal switch: analysis of 19,414 patients.
Article in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 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
backgroundBariatric surgery is being offered to more medically complex patients, including patients on immunosuppressants, although outcomes after different bariatrics surgeries have not been studied in this population.
objectivesWe compared perioperative safety of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and duodenal switch (DS) in patients on immunosuppression.
settingNational sample from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.
methodsThe MBSAQIP database was queried from the years 2015 to 2021 for adult patients on chronic immunosuppression who underwent SG, RYGB, or DS. Revisional, open, endoscopic, or emergency surgeries were excluded, as were patients with an American Society of Anesthesiologists class of 5 and patients without full 30-day follow-up. Propensity-score matching was performed with a 3:3:1 ratio (SG:RYGB:DS) controlling for surgical approach, sex, age, functional status, American Society of Anesthesiologists, body mass index, and comorbidities.
resultsThere were 19,414 patients on immunosuppression who underwent SG (n = 14,358), RYGB (n = 4864), or DS (n = 192). After propensity-score matching , RYGB and DS had longer LOS (P < .01), greater global 30-day complication (P < .01), and 30-day reoperation rates (P = .048). Compared with SG and RYGB, DS had greater rates of patients requiring mechanical ventilation >48-hour postoperatively (P < .05). Compared with SG, DS had greater rates of renal insufficiency (P = .01), organ space infection (P = .01), unplanned intubation (P < .01), and unplanned intensive care unit admission (P < .01).
conclusionsFor patients on immunosuppression, SG carried the lowest complication and reoperation rates, whereas DS had overall complication rates in line with RYGB.
