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

purposeTraditionally, cardiovascular surgeons (CSs) in Japan work long hours. To evaluate the impact of the 2024 Work Style Reform on their work environment, we analyzed how the working conditions of CSs have changed since the reform's implementation.

methodsWe conducted an anonymous web-based survey during a patient-safety session at the 55th Annual Meeting of the Japanese Society for Cardiovascular Surgery.

resultsOf the 1,229 respondents, 1,124 board-certified CSs were included in the analysis. Among them, 64.6% reported working over 60 h per week and 29.5% were unaware of their institution's designated work-hour category. Younger age (adjusted odds ratio [aOR]: 0.594) and employment at a university hospital (aOR: 2.071) were independently associated with extended working hours. Over 80% of respondents reported no significant change in their working hours or job responsibilities post-reform. The availability of nurse practitioners (NPs) or nurses certified in specified medical-acts training (SNs) had no significant impact on workload, although most surgeons perceived their benefit.

conclusionExtended working hours remain prevalent among CSs in Japan despite the implementation of the work-style reforms. Strategic adoption of task-shifting and enhanced staffing is required urgently to ensure the sustainability of cardiovascular surgical care.
