Racial and Ethnic Disparities in Causes for Reoperation and Reintervention Following Bariatric Surgery.
Article in Journal of racial and ethnic health disparities, 2026. 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
backgroundObesity is an epidemic that affects individuals of all races. Literature reports reoperation rates from 0.1 to 6.5% and non-operative reintervention rates from 1.1 to 3.6% after metabolic and bariatric surgery (MBS). Despite discordant rates among ethnic groups being described, results are still inconclusive.
objectiveTo compare reoperation and reintervention causes among ethnic MBS cohorts (setting-Academic Hospital).
methodsRoux-en-Y Gastric Bypass (RYGB) and sleeve gastrectomy (SG) cases were identified from the 2015-2018 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) databases. Regression analyses were performed to determine predictors of reoperation and reintervention. Reoperation and reintervention causes were compared among racial/ethnic cohorts using Pearson chi-square or Kruskal-Wallis tests. A p-value < 0.05 was considered significant.
resultsIn total, 550,671 cases were analyzed. Reoperation and reintervention rates for all-cause and bariatric-related causes were 1.3%, 1.05%, 1.3%, and 1.2%, respectively. The NHB population was identified as an independent predictor of reoperation and reintervention. The most common bariatric-related causes of reoperation were bleeding (22.67%) and leaks (18.07%). NHB had an increased proportion of reoperation due to IO and reintervention due to NVP. For Hispanics and NHW, an increased proportion of bleeding and leaks were significantly increased for both reoperation and reintervention, respectively. After propensity matching, NHB patients undergoing SG had higher odds of reoperation and reintervention due to leaks and bleeding compared to other populations.
conclusionMBS reoperation and reintervention causes differ by ethnic groups. Studies on optimizing care quality based on these disparities should be conducted.
