Population: Per Protocol = ITT for this parameter * Estimates created from an analysis of covariance (ANCOVA) with fixed effects treatment, gender, age (in days), age at the Week 16 measurement (in days) and baseline weightforlength zscore. The numbers of subjects with valid measurements in the PP (PerProtocol) and the ITT (IntentiontoTreat) populations are the same.
