The role of eye tracker in teaching video-assisted thoracoscopic surgery: the differences in visual strategies between novice and expert surgeons in thoracoscopic surgery.

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
Background: In light of continued advances in surgical techniques, it is essential to improve the efficacy of training young thoracic surgeons. Increasingly, the feedback of visual information is believed to be a crucial teaching tool. When surgeons are looking at surgical teaching videos, eye gaze technology can be used to record the gaze movement to examine the stages of information access. Methods: A total of 8 novice surgeons and 8 expert surgeons were recruited to watch an instructional video of surgery while Tobii Pro Fusion was used to recorded their movement trajectory. Another 36 novice surgeons were recruited and divided into two groups. One group watched the video following the trajectory of the senior thoracic surgeons' eye movements and the other group watched the raw video. All 36 novice surgeons subsequently underwent a post-test which was conducted via a questionnaire. Results: The differences in eye fixation patterns and search strategies between novices and experts were assessed using 4 indexes, including total duration of fixation, time to entry saccade, number of saccades, and peak velocity of saccade. The results were compared using independent-sample Conclusions: Novice and expert surgeons have different eye fixation patterns and search strategies when watching videos of thoracoscopic surgery. Watching surgical videos marked with expert eye movement trajectories is conducive to novice surgeons to master operative skills.
