Impact and characteristics of two- and three-dimensional forceps manipulation using laparoscopic hepaticojejunostomy mimicking a disease-specific simulator: a comparison of pediatric surgeons with gastrointestinal surgeons.

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
purposeThis study assessed the impact of 2D and 3D environments by comparing pediatric surgeons (PS) and gastrointestinal surgeons (GIS) using a laparoscopic hepaticojejunostomy simulator.
methodsWe developed a high-fidelity simulator of laparoscopic hepaticojejunostomy. Thirty-five participants (19 PS and 16 GIS) performed hepaticojejunostomy in both 2D and 3D environments. We evaluated the required time, total path length, and average velocities of bilateral forceps in both situations using the para-axial port layout.
resultsRegarding the participants' characteristics, the performance history of laparoscopic hepaticojejunostomy differed significantly between PS and GIS. In PS, the 3D environment did not markedly affect compared with 2D. In GIS, however, the 3D environment affected the time and movement of the right forceps. There were no significant differences in the time between PS and GIS in either environment. In both environments, the right-hand movement of the PS group was shorter and slower than that of the GIS group, but the left-hand movement was the opposite.
conclusionThere were significant differences in forceps movement characteristics between the PS and GIS. The effects of a 3D environment could not be clarified in this study, because it may depend on the port layout used and the operative procedures.
