    BackgroundFemale participants are underrepresented in randomised control trials conducted in urgent care settings. Although sex and gender are frequently reported within demographic data, it is less common for primary outcomes to be disaggregated by sex or gender. The aim of this review is to report sex and gender of participants in the primary papers published on research listed on the National Institute of Health and Care Research (NIHR) Trauma and Emergency Care (TEC) portfolio and how these data are presented.MethodsThis is a systematic review of the published outputs of interventional trials conducted in UK EDs. Interventional trials were eligible to be included in the review if they were registered on the NIHR TEC research portfolio from January 2010, if the primary paper was published before 31 December 2023 and if the research was delivered primarily in the ED. Trials were identified through the NIHR open data platform and the primary papers were identified through specific searches using MedLine, EMBASE and PubMed. The primary objective of the review is to quantify the proportion of sex-disaggregated or gender-disaggregated primary outcomes in clinical trials within UK emergency medicine.ResultsThe initial search revealed 169 registered research projects on the NIHR TEC portfolio during the study period, of which 24 met the inclusion criteria. Overall, 76 719 participants were included, of which 31 374 (40%) were female. Only one trial (CRYOSTAT-2) reported a sex-disaggregated analysis of the effect of the intervention on either primary or secondary outcomes, and no sex-based difference in treatment effect was detected.ConclusionsFewer females than males were included in TEC trials from 2010 to 2023. One trial reported the primary outcome stratified by sex. There is significant scope to increase the scientific value of TEC trials to females by funders.© Author(s) (or their employer(s)) 2024.
