Performance using a visuo-haptic surgical simulator is affected by age.
Article in Advances in simulation (London, England), 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
backgroundSurgeons need to master many manual skills, which potentially decrease with age. Yet, there is no standardized approach to objectively assess how aging affects basic surgical performance and skills training. In this context, simulation offers a promising solution, being widely used to train and test novice clinicians. This study aims to evaluate the impact of age on performance using a visuo-haptic surgical simulator.
methodsA total of 39 participants were divided in two groups: 20 young (20-40 years) and 19 older adults (50-70 years). All participants completed multiple repetitions of three basic surgical tasks using a custom visuo-haptic simulator: incision, an adapted version of the needle threading task, and suturing. Performance metrics such as errors, trajectory, and task duration were compared between groups and across repetitions.
resultsYounger participants outperformed older ones in all tasks. Specifically, they cut more tissue, made fewer errors in the dexterity task, and sutured faster. Both groups partially improved with practice, although older subjects improved less than younger ones.
conclusionsAltogether these results suggest that age significantly affects performance in basic surgical tasks; moreover, older subjects might benefit from periodic training sessions to maintain their skills. In this regard, visuo-haptic simulation can serve as an effective training and evaluation tool to assess and counteract the effects of aging on surgical ability.
