 *Pvalues derived from the univariable screening for the differences in means between the two groups of lameness prevalence (high ≥ 16%, low < 16%)
 ^{a}Annual mean cow mortality rate
 ^{b}Bulkmilk somatic cell count × 1000 cells/mL
 ^{c}Proportion of lean cows at slaughter out of total number slaughtered per herd (%)
 ^{d}Standard deviation (SD) of age at first calving in months
