             plasma GH level of ≤7 ng/ml, determined by central laboratory using a validated assay

          3. Bone age (BA) is not older than chronological age and should be no greater than 9
             years for girls and 10 years for boys.

          4. Without prior exposure to any r-hGH therapy.

          5. Normal birth size, birth weight and length for gestational age

          6. Impaired height and height velocity defined as:

               1. Height (HT) of at least 2.0 standard deviations (SD) below the mean height for
                  chronological age (CA) and gender according to the standards from Prader et. al,
                  1989 , (HT SDS ≤ -2.0).

               2. Annualized height velocity (HV) below the 25th percentile for CA (HV <-0.7 SDS)
                  and gender according to the standards of Prader et al (1989). The interval
                  between two height measurements should be at least 6 months before inclusion.
