Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
ITT Population. All observed data from all scheduled visits (including early termination visits) were included in the MMRM analysis. Data collected at the early termination visits were mapped into the following scheduled visits.
