Handedness in surgical education: Evaluating suturing proficiency among left- and right-handed trainees.
Article in Surgery open science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Left-handedness is often perceived as a disadvantage in surgical training due to the predominance of right-handed instruments and right-handed mentors. Whether this affects the performance of left-handed trainees remains unclear. This study aims to compare the suturing proficiency of left-handed and right-handed novice learners when taught by right-handed instructors using right-handed tools. Methods: A prospective, non-randomized, non-inferiority trial was conducted among students without prior suturing experience, divided by handedness. Participants underwent a teaching session on simple interrupted suturing using right-handed instruments and were assessed using a validated ten-item checklist. Secondary outcomes included satisfaction and were assessed via subjective questionnaires. Results: Among 129 participants (86 right-handed, 43 left-handed), no significant difference in suturing performance was observed between groups. However, left-handed participants reported subjective difficulties using right-handed instruments, and instructors noted challenges teaching them. Conclusion: Handedness does not impact the final outcome of basic surgical skills teaching. However, left-handed students may perceive more challenges due to right-handed tools and techniques. Tailoring teaching strategies and providing hand-specific tools may improve their learning experience.
