Missing values in the secondary outcomes were accounted for using SAS Proc Mixed28 under a missing at random assumption.
Significant changes in all outcomes were observed from Month 0 to Month 6 (all P values < 0.001) for the total study population, but there were no significant differences among the three groups on any outcomes prior to the start of the randomized, extended-care phase at Month 6.
