(A, B) Receiver operating characteristic (ROC) curves of Rab35 serum level. The ROC area under curve (AUC) for PD were 0.664 (95% CI, 0.605-0.722) vs. NC, 0.601 (95% CI, 0.522-0.680) vs. PSP and 0.690 (95% CI, 0.623-0.756) vs. MSA. 95% CI: 95% confidence interval. (C) Distribution of the level of Rab35 in male and female PD groups. The expression of Rab35 was measured by ELISA assay. There were no significant differences in gender between the PD group (F=106, M=107, p=0.7775). (D-F) Correlation analysis of serum Rab35 levels in (D) MSA (n=80, p=0.1686), (E) PSP (n=47, p=0.2085) and (F) healthy control subjects (n=177, p=0.2678). Abbreviation: F, female; M: male.
