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.
FAS included all randomized participants who received at least 1 dose of study treatment and had at least 1 post-baseline measurement. Missing values due to participant dropping due to any reason were imputed using NRI. Here 'N' (Number of Participants Analyzed) signifies participants who were evaluable for this measure.
