Notes: Within genders, participants are ordered by their expressivity score. MoCA = Montreal Cognitive Assessment, GDS = Geriatric Depression Scale, Expr = trained coder rated expressivity, UPDRS face = Unified Parkinson Disease Rating Scale Facial Item Rating, Disease severity = Hoehn and Yahr disease severity rating, corresponding numerical scores are in parentheses; Statisitics in the row Sample are mean or medians for the whole sample of 55 participants from which the 8 participants were purposefully selected.
