Subject demographic data.

Subject age, which was relatively normally distributed, is shown as mean±SD, together with age range. Gender is summarized as the percentage of male subjects in each group. Data for disease duration and Parkinson rating scales are presented as median and range because of the skewed nature of their distributions. Statistical comparisons relating to disease duration and Parkinson's disability scales were performed only between PD and APS patients. (RBD = rapid eye movement sleep behavior disorder; APS = atypical Parkinson syndromes; PD = typical Parkinson’s disease; CTL = clinically normal controls; UPDRS = Unified Parkinson’s Disease Rating Scale; NA = not applicable;ap受试者年龄呈近似正态分布，以均值±标准差（mean±SD）及年龄范围进行报告。性别以各组男性受试者所占百分比进行汇总统计。鉴于疾病病程与帕金森评定量表的分布呈偏态，两类数据均以中位数及极差呈现。针对疾病病程及帕金森残疾量表的统计学比较，仅在典型帕金森病（PD, typical Parkinson’s disease）患者与非典型帕金森综合征（APS, atypical Parkinson syndromes）患者之间开展。（注：RBD=快速眼动睡眠行为障碍（rapid eye movement sleep behavior disorder）；APS=非典型帕金森综合征（atypical Parkinson syndromes）；PD=典型帕金森病（typical Parkinson’s disease）；CTL=临床正常对照（clinically normal controls）；UPDRS=统一帕金森病评定量表（Unified Parkinson’s Disease Rating Scale）；NA=不适用（not applicable））
