Effect of Patient Body Mass Index on Laparoscopic Surgical Ergonomics.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundMinimally invasive surgery may introduce new ergonomic challenges for surgeons. Increased patient body mass index (BMI) may further add to this ergonomic stress.
objectivesThe objective of this study was to quantify the ergonomic impact of patient BMI on surgeons during laparoscopic surgery.
settingUniversity Hospital, USA.
methodsThis prospective cohort study analyzed five minimally invasive surgeons during 24 laparoscopic procedures. Each subject's muscle stress was assessed by recording surface electromyography (EMG) data from eight upper body muscle groups during laparoscopic procedures. EMG data was normalized against the maximal voluntary contraction (MVC) of each muscle measured before the start of surgery to create a percentage of the MVC value (%MVC). Subject workload was assessed through the NASA Task Load Index (NTLX). Statistical analysis was used to determine significance between surgeons operating on patients with or without obesity for %MVC and NTLX scores.
resultsThere was no significant difference (p > 0.05) in both the average muscle activation of all eight muscle groups and NTLX scores during laparoscopic surgery in surgeons operating on patients with BMI > = 30 compared with patients with a BMI < 30.
conclusionsWe detected no differences in ergonomic stress or workload for surgeons operating on patients with or without obesity. For surgeons, the laparoscopic approach may offer an additional advantage over open surgery in patients with obesity. This advantage may be due to an "equalizing effect" of laparoscopy-that surgical ergonomics are less affected by the BMI of the patient when using laparoscopic tools.
