Longer hours, limited returns? a post-hoc National survey analysis of overtime hours during surgical training in Japan.
Article in Surgery today, 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
purposeTo investigate the amount of overtime hours in relation to surgical training outcomes in Japan.
methodsData from a nationwide online questionnaire survey of newly certified surgical trainees were analyzed based on the amount of overtime. Respondents were divided into 2 groups: Group L had worked > 80 h per month, and Group S had worked ≤ 80 h per month. Differences in training outcomes, workplace environments, and challenges were analyzed.
resultsAmong 1410 surgical trainees, 694 respondents who gave valid answers were classified into Group L (n = 462, 67%) and Group S (n = 232, 33%). No significant differences were observed in terms of the number of surgeries (p = 0.95), scientific papers (p = 0.38) or annual income (9.11 vs. 9.46 million JPY, p = 0.94). The proportion of respondents who considered dropping out, felt harassed, or dissatisfied was significantly higher in Group L than in Group S (p = 0.0001, p < 0.0001, and p = 0.0076, respectively).
conclusionIncreased overtime hours did not correlate with positive outcomes such as the number of surgeries performed, scientific publications, or annual income. In contrast, negative outcomes, such as dropout thoughts and feelings of harassment, increased. These findings imply that less overtime and improved overtime management could make surgery more appealing to future applicants.
