The levels of neurotransmitters in CSF of PD-RLS and PD-NRLS groups. Two-tailed t test was used for the comparison of the levels of acetylcholine (Ach) and adrenaline (NE) in CSF between PD-RLS and PD-NRLS groups; Nonparametric test was used for the comparison of the levels of dopamine (DA) and 5-hydroxytryptaphanein (5-HT) in CSF between PD-RLS and PD-NRLS groups. **P < 0.01.
