Proportion of Female Physicians in a Specialty and Median Annual Payments in Ontario, Canada.
Article in JAMA network open, 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
Importance: It is unclear why areas of medicine overrepresented by female physicians receive lower pay. One theory is devaluation-that work done by women is systematically devalued over time. Objective: To assess whether an increase in the proportion of female physicians in a specialty is associated with a decrease in the median annual payments for that specialty. Design, Setting, and Participants: In 2022, a population-based, repeated cross-sectional analysis was conducted using routinely collected data of all active physicians in Ontario, Canada, from 1992-1993 (1993) to 2019-2020 (2020). For each year, the percentage of female physicians and total annual median payments for each specialty were calculated. Main Outcome and Measure: Random-effects linear regression models were constructed to evaluate the association between the percentage of female physicians and median payments overall. Additionally, we conducted a sensitivity analysis of the subgroup of physicians with 1.0 or more full-time equivalency (FTE). Results: The physician workforce increased from 18 572 in 1993 to 31 374 in 2020 with the number of female physicians increasing from 4151 (22.3%) to 13 205 (42.1%). The mean (SD) age for all physicians in 2020 was 49.6 (12.8) years, and for female physicians in 2020 was 46.2 (11.5) years. Median annual payments increased from $183 033 to $316 570. Regression results found that an absolute 1 percentage point increase in the percentage of female physicians in a specialty over 1 year was associated with a $2183 lower increase in median payments than expected overall (95% CI, -$3932 to -$434; P = .02) and a $3235 lower increase for female physicians (95% CI, -$4888 to -$1583; P < .001), but not for male physicians (-$554; 95% CI, -$2373 to $1264). Conclusion and Relevance: This repeated cross-sectional study did not find evidence to directly support the theory of devaluation, yet the results underscore that occupational segregation, both across and within specialties, is associated with the gender pay gap. These findings should prompt medical leaders and policymakers to reconsider what activities are monetarily valued in medicine and whether these align with what patients and the public consider most valuable from a care perspective.
