| Change in SD Score of Body Weight | Change from baseline (week 0) in standard deviation (SD) score of body weight was evaluated after 26 weeks of randomisation. SD-scores are defined to be able to normalise the body weight in the various age groups. To estimate the growth of children, standardised weight is calculated for each year of age and for each sex. Thus, a child with a weight equal to the mean value for its age and sex has an SD score of 0, while a child with a weight 2 SDs above the mean value for its age and sex has an SD score of +2. The SD scores are derived from the age and sex of the subjects and the body weight together with growth curves defined for a reference population. The results are based on the last on-treatment value. Number of participants analysed = number of participants contributed to the analysis. | Week 0, Week 26 | 
| Change in SD Score of Body Mass Index | Change from baseline (week 0) in SD score of BMI was evaluated after 26 weeks of randomisation.

Number of participants analysed = number of participants contributed to the analysis. | Week 0, Week 26 |
