Characterization and Risk Factors for Early Biliary Complications Following Elective Bariatric Surgery: an Mbsaqip Analysis.
Article in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
introductionPatients undergoing bariatric surgery are at risk of postoperative biliary complications. This study aims to characterize biliary complications occurring within 30 days of bariatric surgery and to determine factors associated with their occurrence. METHODS AND PROCEDURES: The 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was analyzed comparing patients with early biliary complications to those without. Early biliary complications were defined by any reoperation, reintervention, or readmission due to gallstones within 30 days of surgery. Patients undergoing elective sleeve gastrectomy or Roux-en-Y gastric bypass (RYGB) were included; patients with prior surgery were excluded. Bivariate analysis compared groups using chi-squared for categorical data and ANOVA for continuous data was performed. Multivariable modeling was performed to determine factors independently associated with early biliary complications.
resultsWe evaluated 750,498 patients with 691 (0.1%) experiencing early biliary complications. Patients with early biliary complications were more often female (87.7% vs 79.6%, p < 0.001). Patients with early biliary complications required significantly more reoperations (86.0% vs 1.1%, p < 0.001), readmissions (82.5% vs 3.6%, p < 0.001), and reinterventions (15.8% vs 1.2%, p < 0.001). Female gender (OR 1.89; CI 1.47-2.44; p < 0.001), postoperative weight loss (OR 1.08; CI 1.06-1.09, p < 0.001), and LRYGB (OR 1.51, CI 1.27-1.79; p < 0.001) were substantial independent predictors of early biliary complications.
conclusionsEarly post-bariatric surgery biliary complications occur uncommonly but confer substantial morbidity. Female gender, postoperative weight loss, and RYGB are the greatest predictors for early biliary complications. Evaluation of preventative measures in these high-risk groups is needed.
