Table 2.

Results from a multivariable mixed effects model accounting for censoring (metobit), showing that the site at which the pressure algometer was applied, the operator and calf identity significantly affected the MNT measured over the thoraces of calves.

Variable	Coefficient	95% CI	P-value
Site 1	Reference
Site 2	1.47	0.52–2.41	0.002
Site 3	0.18	−0.78–1.15	0.709
Site 4	2.08	1.13–3.03	<0.0001
Site 6	2.84	1.89–3.78	<0.0001
Operator B compared to A	−1.36	−1.95–0.78	<0.0001

Calf identity variance estimates = 5.41 (95% CI = 3.17–9.24) P < 0.001.

Intraclass correlation coefficient = 0.198 (95%CI = 0.13–0.30).
