Figure 6

Correlations between pS-α-syn-RBC and scores for motor and nonmotor symptoms of MSA. Correlations between pS-α-syn-RBC levels and scores for motor and nonmotor symptoms were investigated using a multivariate linear regression model adjusting age, gender, and/or disease duration. Disease duration (a); H&Y stage (b); UMSARS II, Unified Multiple System Atrophy Rating Scale part II (c) and IV (d); RBDQ-HK, Rapid eye movement (REM) sleep behavior disorder questionnaire-Hong Kong (e); MoCA, Montreal Cognitive Assessment (f).
