The markers with two-sided variant are presented in the same sub-plot and denoted by L for left side and R for the right side. In the figure the centerlines denote feature medians, bounds of boxes represent 25th and 75th percentiles, whiskers denote nonoutlier data range and the crosses denote outlier values. Statistically significant differences after Bonferroni adjustment are denoted by asterisks: ***p < 0.001. PD = Parkinson’s disease; HC = healthy controls.
