pbRBD	0.62	0.28	1.86	1.08 to 3.21	0.025
MDS-UPDRS part I score	0.25	0.04	1.29	1.19 to 1.40	<0.001
MDS-UPDRS part II score	0.13	0.04	1.14	1.06 to 1.22	<0.001

SCOPA-AUT: Scales for Outcomes in Parkinson’s Disease-Autonomic dysfunction; CI: confidence interval; PD: Parkinson’s disease; pbRBD: probable REM Sleep Behavior Disorder; MDS-UPDRS: Movement Disorders Society-Unified Parkinson’s Disease Rating Scale; S&E: Schwab and England Activities of Daily Living scale; SE: standard error. The regression model was statistically significant (), explained 37.0% of the variance in SCOPA-AUT scores of ≥10, and correctly classified 75.8% of cases.
