1 N: number of cows with the different number of lesion subtypes, also please note that one cow can have several lesion subtypes present at the same time and therefore one cow can be registered at more than one level; 2 Estimate of the probability of testing HF positive with the given amount of lesion subtypes; 3 SE: standard error of the estimate.
