Primary Outcome Measures
NameTimeMethod
Ht SDSca (Height Standard Deviation Score for Chronological Age)Baseline

Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age

Change of yearly growth velocity from baseline to 26 weeksBaseline, 26 weeks after initiating treatment

Height velocity calculate by formula

Ht SDSca26 weeks after initiating treatment

Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age

Secondary Outcome Measures
NameTimeMethod
Skeletal maturityBaseline,26 weeks after initiating treatment

Skeletal maturity=(Bone Age at 26 weeks-Bone Age at baseline)/treatment duration

IGF-1 SDS (IGF-1 Standard Deviation Score)Baseline,26 weeks after initiating treatment
Ht SDSBA (Height Standard Deviation Score for Bone Age)Baseline,26 weeks after initiating treatment
IGFBP-3 SDS (IGFBP-3 Standard Deviation Score)Baseline,26 weeks after initiating treatment
