Reliability Volume: a novel metric for surgical skill evaluation.
Article in Frontiers in medicine, 2025. 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
This study introduces Reliability Volume (RV), an integrated metric combining trajectory similarity with empirical reliability estimation using threshold counts to evaluate surgical skill during repetitive training. RV quantifies both spatial precision and the probability of consistent task execution, addressing limitations of single-session metrics that neglect fatigue and performance drift. Applied to knot-tying with assistive devices, RV jointly reflects spatial accuracy and performance consistency over multiple sessions. Our results show that RV reliably tracks learning progression and is readily compatible with real-time (closed-loop) feedback systems, providing a dynamic, comprehensive, and practice-oriented assessment framework.
