Factors contributing to the variability of a predictive score for cranial cruciate ligament deficiency in Labrador Retrievers

Table 4 Pearson’s correlation coefficients of the differences between investigators for CCLD score, and differences of TPA, FAA, mediolateral distance, and ventrodorsal distance

	Overall (N = 222)	Actual limb status

Difference of TPA	0.84 (< 0.0001)	0.78 (< 0.0001)	0.75 (< 0.0001)	0.87 (< 0.0001)
Difference of FAA	0.70 (< 0.0001)	0.67 (< 0.0001)	0.58 (< 0.0001)	0.81 (< 0.0001)
Difference of mediolateral distance	0.48 (< 0.0001)	0.21 (0.1601)	0.25 (< 0.0001)	0.75 (< 0.0001)
Difference of ventrodorsal distance	−0.42 (< 0.0001)	−0.49 (0.0005)	−0.45 (< 0.0001)	−0.27 (0.1902)
