1 · What the graph read from it

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.

2 · The registry

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 compare the surgical training outcomes of female versus male surgeons in Japan.

methodsWe conducted a secondary analysis of a nationwide online questionnaire survey from 2023, targeting newly certified surgical trainees in Japan.

resultsAmong 757 respondents, 194 (25.6%) self-reported being female. Female trainees were less likely to be married (57% vs. 80%) or have children (25% vs. 48%), and more likely to have a full-time working spouse (85% vs. 42%). Subspecialty preferences differed, with breast surgery favored by female surgeons (34%) and gastrointestinal surgery favored by male surgeons (59%). The number of surgeries performed under general anesthesia, academic papers published, and training program satisfaction did not differ. However, female trainees reported fewer monthly night shifts (median 4 vs. 5, p < 0.01), lower annual incomes (7.57 million vs. 9.82 million JPY, p < 0.01), and that they were more likely to work fewer than 80 monthly overtime hours (41% vs. 31%, p = 0.02), with these gaps being more prominent among those with children.

conclusionFemale and male surgical trainees performed similar numbers of operations under general anesthesia, had similar numbers of academic publications, and had similar levels of training satisfaction. However, the gaps in working hours and salary remain concerning issues requiring further investigation and action.
