Table 1 Results from the multivariable logistic regression analyses for occurrence of metabolic diseases by treatment during the first 12 d after calving. Initial models included treatment (combined treatments), parity category (forced in the final models) and the interaction treatment by parity. As no significant effect for the interaction treatment by parity was established, this term was removed from the models
