| Height Velocity SDS- Week 156 | The height velocity was calculated as the difference between current height and height at baseline (week 0) divided by time between those measurement time points and multiplied by 365 days. Height velocity SDS was calculated using following formula: Z=[(value /M)^L - 1] / S*L; where L, M and S are median (M), skewness (L) and variation coefficient (S) of children/adolescents' height provided for each sex and age. For each subject, a standard deviation score Z (SDS) was calculated based on age and sex referring to the values L, M and S. The method is described in the WHO Multicentre Growth Reference, which also contains the values for L, M and S by age and sex. For Z (SDS) scores below -3 and above 3, the score was adjusted as described in the WHO instruction. This outcome measure is applicable only for the Liraglutide 1.8 mg treatment arm. | Week 0, week 156 | 
| Change From Week 52 in Height SDS- Week 156 | Change in height SDS from week 52 to week 156. Height SDS was calculated using the following formula: Z=[(value /M)^L - 1] / S*L; where L, M and S are median (M), skewness (L) and variation coefficient (S) of children/adolescents' height provided for each sex and age. For each subject, a standard deviation score Z (SDS) was calculated based on age and sex referring to the values L, M and S. The method is described in the WHO Multicentre Growth Reference, which also contains the values for L, M and S by age and sex. For Z (SDS) scores below -3 and above 3, the score was adjusted as described in the WHO instruction. All available data were used for the analysis including data collected after treatment discontinuation and initiation of rescue medication. This outcome measure is applicable only for the Liraglutide 1.8 mg treatment arm. | Week 52, week 156 | 
| Change in Pubertal Assessment/Progression (Tanner Staging)- Week 156 | Pubertal development was assessed in 3 areas (breast, penis and pubic hair development) by the Tanner staging in accordance with stages I-V, where stage I represents pre-adoloscent development and stage V represents pubertal development equivalent to that of an adult. The Tanner staging assessment was no longer required to be performed once a subject reached the Tanner stage V, as judged by the investigator. Reported results are number of subjects at different Tanner stages at week 52 and week 156. This outcome measure is applicable only for the Liraglutide 1.8 mg treatment arm. | Week 52, week 156 | 
| Change From Week 52 in Bone Age Assessment (X-ray of Left Hand and Wrist)- Week 156 | Change in bone age from week 52 to week 156. This outcome measure is applicable only for the Liraglutide 1.8 mg treatment arm. | Week 52, week 156 |
