Cost variance across obesity class for women undergoing laparoscopic hysterectomy by high-volume gynecologic surgeons.
Article in Journal of robotic surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Health-care costs are affected by obesity with both the direct and indirect costs of health care increasing as body mass index (BMI) increases. However, one important aspect of obesity that lacks rigorous study is what impact BMI has on direct surgical cost. We performed a retrospective cohort study of women undergoing a laparoscopic hysterectomy at our single academic university center between January 2012 and December 2017. Women were excluded if their surgery was performed by anyone other than those surgeons with subspecialty training in minimally invasive gynecologic surgery (MIGS), if their hysterectomy was performed by a modality other than conventional laparoscopy or with robotic assistance, or if the indication for hysterectomy was related to any gynecologic malignancy. We identified 600 patients who underwent laparoscopic hysterectomy during the study period. Women who underwent robotic hysterectomy, compared to laparoscopic, had a shorter operative time, lower estimated blood loss, and shorter length of stay. Mean direct cost (± standard deviation) for the cohort was $6398.53 ± $2304.67, age was 44.5 ± 7.5 years, and BMI was 32.2 ± 7.6. Direct cost for all laparoscopic hysterectomies was evaluated across the five different BMI quintiles and no significant difference between groups was found. There was no significant difference in direct cost across procedures between obese and non-obese patients (p = 0.62) and this remained true when separated out by surgical modality. However, when evaluating morbidly obese patients, there appears to be a trend toward cost reduction with robotic hysterectomy compared to conventional laparoscopy. It does not appear that BMI has a statistically significant impact on direct cost between robotic-assisted and conventional laparoscopic hysterectomy. However, these findings may be due to surgical proficiency and warrant further investigation among surgeons with lesser volume.
