Fig. 2

a PSV and PIV diagrams. Violin and box plots comparing b PV, c PSV, and d PIV volumes between the combined PD-PIGD and HC groups using independent samples t tests (t values and p values are shown). Violin and box plots comparing e PV, f PSV, and g PIV volumes across the four groups (HC, HY1, HY2, and HY3-4). The F values and p values shown for these four-group comparisons were obtained by one-way ANCOVA adjusted for age. Post hoc pairwise comparisons utilized Bonferroni correction. In panel f, an asterisk (*) indicates a significant difference (p < 0.05, Bonferroni-corrected, age-adjusted) for the comparison between the HY1 group and the HC group. Bold font for p values reported on the figure indicates statistical significance (p < 0.05). PIV posterior inferior vermis, PSV posterior superior vermis, PV posterior vermis.
