AI model predicts patient outcomes from surgical gestures and provides insights into explainability.
Article in npj digital surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Effective surgical training requires relatively immediate feedback as to outcomes. This makes surgical learning problematic as some surgical outcomes may take months or years to become apparent. The sequence of surgical gestures, the smallest discrete actions of surgery, during the nerve-sparing step of robot-assisted radical prostatectomy has been used to predict 1-year erectile function (EF) outcomes after surgery. To improve this prediction and extract clinically meaningful insights, we describe the addition of anatomic and functional context to surgical gestures. We analyzed surgical video of 147 patients at 5 surgical centers undergoing robotic-assisted radical prostatectomy. The addition of anatomic and functional characterization to surgical gestures improved model prediction of post-operative EF from 0.78 [95%CI: 0.60, 0.92] to 0.85 [95%CI: 0.66, 0.96]. Aggregated attention weight analysis identified novel gesture, anatomy, and function combinations contributing most to EF outcomes. The identification of these critical gestures provides a starting point for more data-driven training in clinical practice.
