Mean difference in free-water-corrected fractional anisotropy values in each region of interest for Parkinson’s disease-control (top), MSA-control (middle), and PSP-control (bottom). ASN = anterior substantia nigra; CC2 = corpus callosum region 2; CN = caudate nucleus; LB VI = cerebellar lobule VI; MCP = middle cerebellar peduncle; MSA = multiple system atrophy; PD = Parkinson’s disease; PSN = posterior substantia nigra; PSP = progressive supranuclear palsy; PUT = putamen; SCP = superior cerebellar peduncle; STN = subthalamic nucleus; THA = thalamus; VER = vermis. Asterisks denote a significant difference after correction for multiple comparisons.
