Existing research guidelines for inclusive trials methodology. Working toward the integration of qualitative research, equity, diversity, and inclusion and trials methodology: a focused mapping review

Current inclusion guidance is concentrated in the early stages of trial design, with limited attention to later trial stages. Qualitative research offers a valuable way to address these gaps by capturing participant perspectives and supporting inclusive practices across the trial lifecycle. This review provides a foundation for developing practical tools to guide more inclusive trials, with the next phase involving coproduction of guiding principles with interest holders.
