Outcome results
Glycosylated Hemoglobin (HbA1c) Value at 12 Week Endpoint
Glycosylated hemoglobin reflects the average blood glucose level over the previous 12 weeks of treatment.
Time frame: Baseline and 12 weeks of each treatment
Population: Includes all randomized patients who completed the study with no major protocol violations. Crossover study design allows for the comparison of the effect of two treatments on the same patients, each patient served as own control for between-treatment comparisons. The data from two periods were combined and analyzed.
