*
Denotes significant difference (p < 0.05) between control and case dogs. pa refers to p value adjusted for multiple comparisons.
MEP, motor evoked potential; CV, conduction velocity; MNCV, motor nerve conduction velocity; SD, standard deviation; ms, milliseconds; m/s, meters per second; mA, milliamperes; NA, not applicable.
