Enhancing Laparoscopic Simulation Skills Through Nondominant Hand Training in Daily Activities.
Article in Cureus, 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
Background Being in the large majority, right-handed people are not required to use their nondominant hands throughout their daily lives, resulting in a loss of motor dexterity. As technology continues to advance, improving motor dexterity in nondominant hands has proven to be not only advantageous but imperative for surgeons. In this study, we assessed how increasing the use of participants' nondominant hands impacted proficiency during laparoscopic simulator tasks. Methods A total of 18 preclinical medical students, divided into experimental and control groups, were timed twice on three laparoscopic simulator tasks. The experimental group spent three weeks between testing phases using their nondominant hand for daily activities and recording compliance through a daily survey. Results Compared to the control, the experimental group showed a significant improvement in proficiency for two of the tasks (p<0.05). No participants in this group successfully completed the task requiring the greatest motor dexterity during either testing phase. Additionally, all nine experimental participants (100%) reported feeling substantially more confident in their laparoscopic abilities during the post-test. Conclusion This study examined whether incorporating nondominant hand use into daily activities could improve laparoscopic task performance among preclinical osteopathic medical students. Results suggest that short-term, self-directed ambidexterity training may enhance basic laparoscopic skills and learner confidence, though gains in fine motor control were limited. This study can encourage physicians and residency programs to incorporate nondominant hand use into their curriculum and everyday life.
