Primary Outcome Measures
NameTimeMethod
Change From Baseline in Height Standard Deviation Score (SDS) for Chronological Age (CA) at Month 36: Full Analysis PopulationBaseline, Month 36

Height was measured using a wall mounted device (example, Harpenden stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded. Height SDS CA Yx = (height Yx - reference mean for CA Yx) / reference SD for CA Yx; Yx refers to the value at particular timepoint x. Height in SDS was calculated using Sempe reference means and SD for height. CA calculated as integer (Date of height measurement-Date of birth)/365.25\*12.

Change From Baseline in Height Standard Deviation Score (SD) for Chronological Age (CA) at Month 36: Per Protocol (PP) PopulationBaseline, Month 36

Height was measured using a wall mounted device (example, Harpenden stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded. Height SDS CA Yx = (height Yx - reference mean for CA Yx) / reference SD for CA Yx; Yx refers to the value at particular timepoint x. Height in SDS was calculated using Sempe reference means and SD for height. CA calculated as integer (Date of height measurement-Date of birth)/365.25\*12.

Secondary Outcome Measures
NameTimeMethod
Mean HeightBaseline, Month 12, 24, 36, 48, 60

The standing height measurements were performed using a wall mounted device (example Harpenden Stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded.

Mean Height Standard Deviation Score (SDS) for Bone Age (BA)Baseline, Month 12, 24, 36, 48, 60

The standing height measurements were performed using a wall mounted device (example Harpenden Stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded. Height SDS BA Yx = (height Yx - reference mean for BA Yx) / reference SD for BA Yx; Yx refers to the value at particular timepoint x. Height in SDS was calculated using Sempe reference means and SD for height. BA was estimated locally using an X-ray from the left wrist and hand.

Annual Growth Rate (AGR)Baseline, Month 12, 24, 36, 48, 60

AGR at Yx was derived by subtracting AGR at baseline from Yx value. AGR was calculated each year and re scaled to 1 year if the interval between Yx and Y\[x-1\] was not 365 days, as long as a participant remained in the study. AGR at Yx was calculated using the previous height measurements (Y\[x-1\]) and height recorded at Yx (AGR Yx = \[height Yx-height Y{x-1}\] / (\[date of Yx - date of Y{x-1}\] /365.25). Yx refers to the value at particular timepoint x.

Growth Rate (GR) Standard Deviation Score (SDS) for Bone Age (BA)Month 12, 24, 36, 48, 60

GR SDS BA Yx = (GR Yx - reference mean for BA Yx) / reference SD for BA Yx; Yx refers to the value at particular timepoint x. GR in SDS was calculated using Sempe reference means and SD for GR. BA was estimated locally using an X-ray from the left wrist and hand.

Body Mass Index (BMI)Baseline, Month 12, 24, 36, 48, 60

BMI was calculated by weight divided by height squared and measured as kilogram per square meter (kg/m\^2).

Growth Rate (GR) Standard Deviation Score (SDS) for Chronological Age (CA)Baseline, Month 12, 24, 36, 48, 60

GR SDS CA Yx = (GR Yx - reference mean for CA Yx) / reference SD for CA Yx; Yx refers to the value at particular timepoint x. GR in SDS was calculated using Sempe reference means and SD for GR. CA calculated as integer (Date of height measurement-Date of birth)/365.25\*12.

Change From Baseline in Height at Month 12, 24, 36, 48 and 60Baseline, Month 12, 24, 36, 48, 60

The standing height measurements were performed using a wall mounted device (example Harpenden Stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded.

Change From Baseline in Height Standard Deviation Score (SDS) for Chronological Age (CA) at Month 12, 24, 48 and 60Baseline, Month 12, 24, 48, 60

The standing height measurements were performed using a wall mounted device (example Harpenden Stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded. Height SDS CA Yx = (height Yx - reference mean for CA Yx) / reference SD for CA Yx; Yx refers to the value at particular timepoint x. Height in SDS was calculated using Sempe reference means and SD for height. CA calculated as integer (Date of height measurement-Date of birth)/365.25\*12.

Change From Baseline in Height Standard Deviation Score (SDS) for Bone Age (BA) at Month 12, 24, 36, 48 and 60Baseline, Month 12, 24, 36, 48, 60

The standing height measurements were performed using a wall mounted device (example Harpenden Stadiometer). The standing height of the participant was measured two times and the mean of these measurements was recorded. Height SDS BA Yx = (height Yx - reference mean for BA Yx) / reference SD for BA Yx; Yx refers to the value at particular timepoint x. Height in SDS was calculated using Sempe reference means and SD for height. BA was estimated locally using an X-ray from the left wrist and hand.

Change From Baseline in Bone Age (BA) at Month 12, 24, 36, 48 and 60Baseline, Month 12, 24, 36, 48, 60

BA was estimated locally using an X-ray from the left wrist and hand.

Ratio of Bone Age (BA) to Chronological Age (CA)Baseline, Month 12, 24, 36, 48, 60

BA was estimated locally using an X-ray from the left wrist and hand. CA at the date of corresponding X-ray (Date of X-ray - Date of birth)/365.25. Ratio of BA/CA at each annual study visit was calculated.
