*The analysis included the primary farm-based characteristics associated with positivity (p<0.10 in likelihood ratio test). The number of observations was 716; the number of levels used was 309 (quasi-likelihood under the independence model criterion 832.88). OR, odds ratio.
†Risk increased per cow.
