Bariatric peri-operative outcomes are affected by annual procedure-specific surgeon volume.

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
backgroundThere is limited data examining specific annual surgeon procedural volumes associated with improvement of postoperative outcomes following Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG).
objectivesEffect of surgeon volume on procedural outcomes.
methodsUsing the SPARCS Administrative database, patients undergoing laparoscopic RYGB or SG between 2010-2014 were analyzed. Multivariable generalized linear mixed regression models were first used to analyze the influences of 3 yearly mean volumes (combined, RYGB and SG mean volumes) on each of three surgical outcomes: 30-day readmission, peri-operative complications, and extended length of stay (LOS), while accounting for patient specific variables.
resultsA total of 46,511 laparoscopic bariatric procedures were included in the study. Risk for any complication and 30-day readmissions following RYGB decreased with increasing RYGB volume up to a specific volume and stayed similar afterward (OR 0.97, 95% CI 0.96-0.98 while volume < 247.9 cases/year and OR 0.99, 95% CI 0.98-0.99 while volume < 354.1 cases/year, respectively) while risk for extended LOS decreased with increasing combined bariatric mean volume up to a specific volume and stayed similar afterward (OR 0.9, 95% CI 0.85-0.95 while volume < 62.1 cases/year). Similar patterns were found for extended LOS and complications following SG (OR 0.82, 95% CI 0.72-0.93 while SG volume < 26.3 cases/year and OR 0.94, 95% CI 0.91-0.98 while combined volume < 62.1 cases/year, respectively), while 30-day readmission following SG significantly increased when combined bariatric volume being more than 138 cases/year (OR 1.10, 95% CI 1.00-1.21 while combined volume > 138 cases/year)).
conclusionsBariatric procedure peri-operative outcomes are affected by procedure-specific annual surgeons' volume.
