Fig. 2: Statistical analysis results of the PVS burden.

From: Diffusion along perivascular spaces as marker for impairment of glymphatic system in Parkinson’s disease

Fig. 2

Comparison of the PVS number (a) and volume (b) between the PD and HC groups. Correlations of right-hemispheric DTI-ALPS index with PVS number (c) and PVS volume (d) in right BG. The error bars represent the standard deviation. *indicates p value < 0.05, **indicates p value < 0.01; ***indicates p value < 0.001. PVS perivascular space, PD Parkinson’s disease, HC healthy control, PDa PD patients whose H&Y stage was lower than or equal to 2, PDb PD patients whose H&Y stage was higher than 2, DTI-ALPSr right-hemispheric diffusion tensor image analysis along the perivascular space, BGr right-hemispheric basal ganglia, scc Spearman correlation coefficient.
