Motor symptoms and non-motor symptoms of PD-RLS and PD-NRLS groups.

	PD-RLS group (88 cases)	PD-NRLS group (130 cases)	P value
Motor symptoms
H-Y stage [stage, median (quartile)]	2.00 (1.50, 2.50)	1.50 (1.00, 2.50)	0.00**
UPDRS III [points, median (quartile)]	26.75 (19.00, 41.75)	20.00 (11.50, 29.00)	0.00**
Levodopa equivalent daily dose [mg, median (quartile)]	1.88 (0.00, 3.75)	0.00 (0.00, 2.50)	0.01*
Non-motor symptoms
HAMD [points, median (quartile)]	15.00 (9.00, 20.00)	8.00 (3.00, 14.75)	0.00**
HAMA [points, median (quartile)]	11.00 (6.00, 19.00)	6.00 (2.00, 11.00)	0.00**
PSQI [points, median (quartile)]	7.00 (5.00, 10.00)	5.00 (3.00, 9.00)	0.00**
MAES (points, mean ± SD)	18.62 ± 8.32	14.70 ± 9.00	0.01*
FSS (points, mean ± SD)	41.27 ± 20.03	20.78 ± 35.45	0.04*
SCOPA-AUTO score [points, median (quartile)]	11.00 (7.00, 18.00)	9.00 (5.00, 28.25)	0.06
MoCA [points, median (quartile)]	20.00 (15.00, 24.75)	21.50 (16.00, 25.00)	0.23

Two-tailed t test was used for the comparison of scores of MAES and FSS between PD-RLS and PD-NRLS groups; Nonparametric test was used for the comparison of motor symptoms and for the comparison of scores of HAMD, HAMA, PSQI, SCOPA-AUTO score and MoCA. H-Y stage = Hohen and Yahr stage; UPDRS = Unified Parkinson Disease Rating Scale; HAMD = Hamilton Depression Scale; HAMA = Hamilton Anxiety Scale; PSQI = Pittsburgh Sleep Quality Index; MAES = Modified Indifference Rating Scale; FSS = Fatigue Severity Scale; MoCA = Montreal Cognitive Assessment; SCOPA-AUTO = Scale for Outcomes in Parkinson Disease for Autonomic Symptoms. *P < 0.05, **P < 0.01.
