    Objectives: To examine the gender distribution of authorship of pediatric critical care randomized control trials. Data Sources: The 415 randomized control trials in pediatric critical care published before 2019. Study Selection: We included all randomized control trials enrolling children in a PICU. We used PICUtrials.net, which uses comprehensive search strategies of multiple databases, to identify published randomized control trials. Data Extraction: We manually extracted the name and profession of each listed author from each publication and classified each author as male or female based on their name. Results: We included 2,146 authors and were able to classify 1,888 (88%) as men or women. Overall, 38% of authors were women, this varied with the authorship position: 37% of first, 38% of middle, and 25% of last authors were women (p < 0.001). The three most common professions were physician (63%), nonclinician (11%), and nurse (6%) - of which 30%, 45%, and 97%, respectively, were women. The percentage of female authorship overall has increased from 28% in 1985-1989 to 39% in 2015-2018 (p for trend = 0.004). There were no significant differences in the characteristics of randomized control trials published with a female first or last author versus those with both male first and last authors with respect to the median number of children randomized (60 vs. 50; p = 0.41), multicentred trials (17% vs. 24%; p = 0.12), trials at low risk of bias (50% vs. 66%; p = 0.26), reporting any funding (55% vs. 51%; p = 0.66), or median number of citations per year (1.5 vs. 2.4; p = 0.09). Conclusions: Although increasing over time, the percentage of researchers publishing pediatric critical care randomized control trials who are women still lags behind the percentage clinicians who are women. Trials that female researchers publish are similar in characteristics and impact as male researchers. Further work should identify barriers to gender diversity and potential solutions in pediatric critical care research. © 2020 Lippincott Williams and Wilkins. All rights reserved.

    BACKGROUND: Clinical trials change practice in cardiology, and leading them requires research training, mentorship, sponsorship, and networking. Women report challenges in obtaining these opportunities. OBJECTIVES: The purpose of this review was to evaluate temporal trends in representation of women as authors in heart failure (HF) randomized controlled trials (RCTs) published in high-impact medical journals and explore RCT characteristics associated with women as lead authors. METHODS: We searched MEDLINE, EMBASE, and CINAHL for HF RCTs published in journals with an impact factor ≥10 between January 1, 2000, and May 7, 2019. We assessed temporal trends in the gender distribution of authors, and used multivariable logistic regression to determine characteristics associated with women as lead authors. RESULTS: We identified 10,596 unique articles, of which 403 RCTs met inclusion criteria. Women represented 15.6% (95% confidence interval [CI]: 12.2% to 19.6%), 12.9% (95% CI: 9.8% to 16.6%), and 11.4% (95% CI: 8.5% to 14.9%) of lead, senior, and corresponding authors, respectively. The proportion of women authors has not changed over time. Women had lower odds of lead authorship in RCTs that were multicenter (odds ratio [OR]: 0.58; 95% CI: 0.18 to 0.96; p = 0.037), were coordinated in North America (OR: 0.21; 95% CI: 0.08 to 0.70; p = 0.011) or Europe (OR: 0.33; 95% CI: 0.09 to 0.91; p = 0.039), tested drug interventions (OR: 0.42; 95% CI: 0.16 to 0.97; p = 0.043), or had men as the senior author (OR: 0.50; 95% CI: 0.21 to 0.93; p = 0.043). CONCLUSIONS: Women are under-represented as authors of HF RCTs, with no change in temporal trends. Women had lower odds of lead authorship in RCTs that were multicenter, were coordinated in North America or Europe, tested drug interventions, or had men as senior authors.

    BACKGROUND: Female authorship opportunities have lagged behind those of their male counterparts, with gender disparities most prominent in surgical specialties. Our objective was to determine trends of female first, last, and first or last authorships across time and surgical specialties and whether female first or last authorship was associated with journal impact factor. STUDY DESIGN: A systematic review of EMBASE (OvidSP), MEDLINE (OvidSP), and Cochrane (Wiley) databases from inception to December 22, 2017 was performed to identify all randomized controlled trials evaluating minimally invasive surgery vs classical surgical techniques. The primary end point was female first, last, and first or last authorship, with gender determined via an online search strategy and verified via Genderize.io. Secondary end point was journal impact factor, recorded from Clarivate Analytics InCites. RESULTS: There were 9,321 articles identified and 489 met our inclusion/exclusion criteria. Sixty-eight (13.9%) first and 60 (12.3%) last female authors were identified. A positive linear trend for female first (R2 = 0.35, Cochran-Armitage test for trend, p < 0.001), last (R2 = 0.30, p < 0.001), and first or last authorships (R2 = 0.40, p < 0.001) over time was identified. This trend was observed across surgical specialties except for orthopaedics. The highest calculated percentages of female first, last, and first or last authorships by the year 2017 were seen in obstetrics and gynecology (33.8%, 32.0%, and 43.8%, respectively), all significantly lower than the corresponding percentage of the female obstetrics and gynecology workforce in 2017 (57.0%). Neither female first nor last authorship positions were associated with journal impact factor. CONCLUSIONS: A significant increase in female first and last authorship in randomized controlled trials of minimally invasive surgical techniques in the last 3 decades has been observed, but continued efforts to bridge this gender gap are sorely needed.
