Rapid eye movement (REM) sleep without atonia (RSWA) values across groups. Participants were grouped by the percentage of REM sleep in which they exhibited RSWA for each of the measured muscles (submentalis or flexor digitorum superficialis). Participants who exhibited RSWA in at least one muscle group were categorized as Parkinson’s disease with RSWA (PD-RSWA+) while those with no RSWA were categorized as Parkinson’s disease without RSWA (PD-RSWA−). There was a significantly higher level of RSWA in the PD-RSWA+ group compared to the PD-RSWA− and control groups (One-way ANOVA, Bonferroni corrected post hoc comparisons, * p < 0.001). Boxes range from the first to the third quartile, whiskers extend to 95% confidence intervals, median is indicated by a line across the box, and mean is indicated by a square marker.
