Z scores for height (upper panel), weight (center panel), and BMI (lower panel) for pediatric subjects. Height (upper panel), weight (center panel), and BMI (lower panel) Z-scores at baseline and 12 months by baseline age categories for pediatric subjects. BMI Z-scores were not available for subjects < 2 years of age. The Z scores are calculated based on mean of US population for that age group. The Z score indicates how many standard deviations the study participants deviate from the average age-corrected US population and a score between − 2 and 2 is typically considered within normal range.
