  1. Population: Per Protocol = ITT for this parameter
  2. * 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 weight-for-length z-score.
  3. The numbers of subjects with valid measurements in the PP (Per-Protocol) and the ITT (Intention-to-Treat) populations are the same.
