Two-dimensional (2D) versus three-dimensional (3D) laparoscopy for vaginal cuff closure by surgeons-in-training: a randomized controlled trial.
Trial report in Surgical endoscopy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02192606 (Does 3D Laparoscopy Improve Vaginal Cuff Suture Time? A Randomized Controlled Trial Comparing 3D Laparoscopy Versus Standard Laparoscopy), which is not on this map. Cited by 12 papers, 2 of them syntheses 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.

Abstract
backgroundObjective evidence is lacking as to the benefit of the addition of 3D vision to conventional laparoscopy in Gynecologic surgery. This study aims to compare 3-D visual system to traditional 2-D laparoscopic visualization for the laparoscopic closure of the vaginal cuff during total laparoscopic hysterectomy by surgeons-in-training [defined as senior OBGYN resident or Minimally Invasive Gynecologic Surgery (MIGS) fellow].
methods51 patients undergoing total laparoscopic hysterectomy at two tertiary care academic hospitals were randomized to two-dimensional or three-dimensional vision system with cuff closure performed by surgeons-in-training. The primary outcome was the time taken for vaginal cuff closure. Secondary outcomes included peri-operative outcomes and assessment of surgeon's perception of ease of cuff closure.
results27 (52.9%) cases were allocated to cuff closure with the 2D system and 24 (47.1%) cases to closure with the 3D vision system. Patient baseline characteristics were similar between the vision systems. Mean vaginal cuff closure time was not significantly different between 2D and 3D vision (10.1 min for 2D versus 12 min for 3D, p = 0.31). An additional 24 s was added to cuff closure time with each 1 kg/m
conclusionWe did not demonstrate any benefits of 3D vision system over conventional 2D for the task of laparoscopic vaginal cuff suturing performed by surgeons-in-training. RCT Registration Number NCT02192606 https://clinicaltrials.gov/ct2/show/NCT02192606 (July 17, 2014).
