Multivariable logistic regression of Hemo-Fec^® (HF) Day 2 test results in relation to abomasal lesion subtypes Ib and Ic.

HF Day 2	Level	Estimate 1	SE 2	p-Value

Lesion subtype Ib	1	0.125	0.176	0.48
	2	0.191	0.220	0.39
	3	−0.071	0.332	0.83
	≥4	0.504	0.162	0.002
Lesion subtype Ic	1	0.043	0.145	0.77
	2	0.305	0.173	0.077
	3	0.395	0.211	0.061
	≥4	0.654	0.181	0.0003

¹ Estimate of the probability of testing HF positive with the given number of lesion subtypes; ² SE: standard error of the estimate.
