Racial disparities in reasons for mortality following bariatric surgery.
Article in Journal of racial and ethnic health disparities, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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.
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
backgroundMetabolic and bariatric surgery (MBS) remains a safe and effective treatment for patients with severe obesity. Recent studies have highlighted racial disparities in perioperative outcomes, including up to a twofold higher mortality rate in non-Hispanic black (NHB) (vs. non-Hispanic white (NHW)) patients. Causality for these disparate outcomes remains unclear and largely unexplored.
objectiveOur study aim was to determine reasons for mortality among racial and ethnic cohorts and MBS patients.
settingAcademic Hospital.
methodsRoux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) cases were identified using the 2015 to 2018 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) database using current procedural (CPT) codes 43,664, 43,645, and 43,775. Multivariate regression analyses were performed to determine independent predictors of overall and bariatric-related mortality. Reasons for mortality were identified and compared between racial and ethnic cohorts.
resultsOf 650,903 RYGB and SG cases, 512,041 were included in our analysis (73% SG). For the entire cohort, all-cause and bariatric-related mortality rates were 0.095% and 0.05%, respectively. Age, male gender, ASA 4, functional status, therapeutic anticoagulation, smoking, COPD, and RYGB were independently associated with both overall and bariatric-related mortality. NHB had increased odds (2.13, p < 0.001) of bariatric-related mortality. Compared to NHW patients (13.3%), venous thromboembolic (VTE) complication was the most common reason for overall mortality in NHB (27.8%) and Hispanic (25%) patients (p < 0.001). VTE-related mortality directly associated with the bariatric procedure was also higher in NHB (34.6%) and Hispanic (33.3%) (vs. NHW 21.0%) patients (p 0.05). When stratified by procedure, mortality causes in RYGB cases were similar between racial and ethnic cohorts. In the SG cohort, the proportion of VTE-related mortality varied significantly (p 0.043) between NHB (39.2%), Hispanic 40.0%, and NHW (20.5%) patients.
conclusionThere are racial and ethnic differences in causes of mortality following bariatric surgery. The predominant cause of overall and bariatric-related mortality in NHB bariatric surgery patients is postoperative venous thromboembolism. More granular MBSAQIP data capture is needed to determine the role of patient risk versus practice patterns in these disparate outcomes.
