Using Tractography to Distinguish SWEDD from Parkinson’s Disease Patients Based on Connectivity Table 3 Identified connections with significant group-wise differences. Significantly different connections are reported in terms of connectivity values and corrected
values. Connectivity values are reported as mean ± standard deviation (SD). Bold text shows identified connections with significant differences (corrected
) between PD and SWEDD.
