Data were analyzed with analysis of variance of factorial design with age and sex as covariates
Binary logistic regression model was used to analyze the relation between SNP and motor complication (wearing-off phenomenon and dyskinesia), with age and sex as covariates
*P < 0.05, aValues are expressed as the mean ± SD; bValues are expressed as the median ± IQ
