  • a Paired t tests were used to compare FA values extracted from WM at rostral (C1–C3), midcervical (C4–5, healthy subjects), or MCL (subjects with DCM), and caudal (C6–C7) levels between no triggering vs triggering in 10 subjects (4 healthy, 6 with DCM). Welch t tests were used to compare test-retest coefficient of variation between no triggering (n = 26) and triggering (n = 10).
