For continuous variables mean, 95% CI and n are presented; For categorical variables n and percent are presented.

a

LSM (95% CI) and P-value are obtained from SAS procedure PROC GLM with sequence, patient(sequence), period, and treatment as class variables.

CV, coefficient of variation; MAGE, mean amplitude of glycemic excursions.
