Estimating Future Obstetrics and Gynecology Workforce Needs in Japan.
Article in Cureus, 2025. 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
Introduction The Ministry of Health, Labour, and Welfare of Japan (MHLW) introduced a regulation on physician overtime work in 2024, limiting overtime hours to a maximum of 960 annually. This regulation has raised concerns that the quality of medical care may decline. On the other hand, the shifting demographics of Japan, characterized by an aging population and declining birth rates, suggest a potential decrease in demand for obstetrics and gynecology (OBGYN) services in the future. In Japan, there is no feasible study regarding how many OBGYN doctors are currently lacking and how many of them will be necessary. Herein, we conduct simulations using Japanese insurance claims data to estimate the required number of OBGYN doctors. Methods This is a simulation study. We project future demand based on the current demand, working hours, and demographic changes. Using health insurance claims data, we estimate how many OBGYN doctors will be necessary in the future within the overtime work limit. Results The required number of doctors shows a declining trend that mirrors the declining population. Presently, there is a shortage of 1,500 doctors to comply with the 960-hour limit, and it is anticipated to be until 2040 or later before all doctors adhere to this limit. Several sensitivity analyses consistently support this trend. Conclusions Despite the existing shortage of obstetricians and gynecologists, future demands are expected to decrease. Inter-hospital and regional communication should be promoted for systemic innovations.
