CI, confidence interval; LF, left front; RF, right front; LH, left hind; RH, right hind; CSM, cervical spondylomyelopathy.
P < .05.
CV, coefficient of variation. CV was only established for selected parameters.
P-value tests if the means are different between normal and affected dogs using a random-effects linear regression.
