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.
Pre-imputation status. Missing data points were excluded and values below the lower limit of quantification (LLOQ) were included in the analysis with an assigned value of assay LLOQ.
