Effect of operative times in bariatric surgery on outcomes: a matched analysis of the MBSAQIP database.
Review in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
backgroundThe implications of operative time (OT) have been studied in different surgical specialties, showing a correlation with higher incidence rates of postoperative complications. However, the impact of OT on bariatric surgery complications is not well elucidated.
methodsA retrospective review of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database between 2015 and 2019 was performed. A total of 358,382 SG patients and 123,357 RYGB patients were included. The median OT was 68 min (10-720) and 113 min (10-640) for the sleeve gastrectomy (SG) group and the Roux-en-Y gastric bypass group, respectively. The groups were subdivided into two subgroups based on OT in comparison to the median time of each group. The subgroups were compared for surgical complications and outcomes. To reduce selection bias and risk of confounders, we performed a propensity score matching (PSM) for 22 variables.
resultsIn the PSM-matched cohort, 18,915 SG and 6,495 RYGB patients were included in each subgroup. The SG cohort showed higher rates of Clavien-Dindo Class 1, 2, 3a, 4, and 5 complications as well as higher rates of readmission, reoperation, and reintervention in the longer OT group before matching. After PSM, the subgroup with longer times continued to have higher rates of Clavien-Dindo Class 2 complications and higher rates of readmission and reoperation. Similarly, there were higher rates of all Clavien-Dindo class complications as well as readmission, reoperation, and reintervention in the RYGB group with higher OT. After PSM, there were still higher rates of Clavien-Dindo Class 3a complications as well as readmission and reintervention in the RYGB subgroup with prolonged OT.
conclusionIn both SG and RYGB, longer OT was associated with increased rates of complications as well as readmission, reoperation, and reintervention. Surgeons should be cognizant of the increased rates of complications when operative times are longer.
