A common outcome set for trials in dementia with Lewy bodies (DLB COS).

Introduction: Methodological heterogeneity in dementia with Lewy bodies (DLB) trials contributes to publication bias and makes evidence synthesis and meta-analysis challenging. We aimed to develop a core outcome set for DLB (DLB COS) trials to improve consistency and comparability in DLB research.

Methods: We conducted a systematic review to identify outcomes and administered a two-stage Delphi survey to a diverse panel of lay and professional stakeholders.
