Table 1. Explanatory categorical variables retained in the logistic regression model with dry cows’ lameness prevalence (0 = visual locomotion score ≤ 2, 1 = visual locomotion score > 2) as an outcome variable.
Least squares means with 95% confidence intervals (CI) and P values are presented.

SEASON: Season at scoring (1 = winter, 2 = spring, 3 = summer, 4 = autumn); BCSG: Body condition score at drying off (1 if BCS < 3; 2 if 3 ≤ BCS < 3.5; 3 if BCS ≥ 3.5); PCHDL: Previous lactation claw horn disruption lesion incidence (0/1); Lactation group (1 if lactation = 1; 2 if lactation = 2; 3 if lactation ≥ 3)
