To improve the precision of the analysis, covariate analyses were conducted. The respective baseline values were used as covariates in the analysis models for all the continuous variables; along with the pre-specified stratification factor, screening HbA1c values (<7.5% and ≥7.5%). The adjusted least squared (LS) means at each time point were reported. Other clinically meaningful baseline covariates and stratification factors were examined; if statistically significant, these factors were included in the analysis models.
