Bariatric surgery operating room time--size matters.
Article in Obesity surgery, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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 goal of this study was to document the relationship between BMI and the components of bariatric surgical operating room (OR) time.
methodsThe Stanford Translational Research Integrated Database Environment identified all patients who underwent laparoscopic Roux-en-Y gastric bypass procedures at Stanford University Medical Center between May 2008 and November 2013. The 434 patients were divided into 3 groups: group 1 (n = 213) BMI ≥35 to <45 kg/m(2), group 2 (n = 188) BMI ≥45.0 to <60 kg/m(2), and group 3 (n = 33) BMI ≥60 kg/m(2). The primary variable measured was total operating room time, defined as beginning when the patient entered the OR until the moment the patient physically left the OR. Secondary variables were anesthetic induction time, nursing preparation time, operation time, time for emergence from anesthesia, and total length of hospital stay.
resultsIncreasing BMI was associated with increased total OR time (group 1 = 202 min, group 2 = 215 min, group 3 = 235 min), mainly due to longer operation time (group 1 = 147 min, group 2 = 154 min, group 3 = 163 min). Anesthetic induction (group 1 = 17 min, group 2 = 18 min, group 3 = 23 min) and emergence times (group 1 = 12 min, group 2 = 12 min, group 3 = 22 min) were also significantly longer in the largest patients.
conclusionsOperating room schedules and plans for resource utilization should recognize that the same bariatric procedure will require more time for patients with BMI >60 kg/m(2) than for smaller bariatric patients.
