1. Growth rate (cm/yr)
Estrogen at age 12
Estrogen at age 15
Expected untreated (Lyon, et al.)
Chronological Age (yr)
Annual growth velocity for patients receiving GH and beginning estrogen at either 12 or 15 yr of age. The mean growth velocity ± 1 SD ist shown (n=11-26 in 12-yr-old group; n=16-29 in 15-yr-old group). Data for untreated patients are from Ref.2.

2. Change in Bone Age (yr)
Chronological Age (yr)
Effect of estrogen on bone age advancement. Patients beginning estrogen at age 12 yr are compared with those that received estrogen after the age of 15 yr. The mean change in bone age occurring each year is plotted ±1 SD. The number of patients analyzed for each grouping is illustrated. The rate of bone maturation was statistically significantly different between the groups (P=0.004)

3. Height gain for patients treated with GH compared to controls
Height gain for patients treated with GH compared to controls. Data are plotted for individual patients with the most recent height minus the pretreatment projected height determined as indicated in the text. The mean values for each group are indicated by a dash. Control patients were matched from a historical database as described in the text
Most Recent Minus Projected Height (cm)
Control (14)
Estrogen at age 12 (26)
Estrogen at age 15 (29)
Control (55)
Estrogen after 1 yr (51)
Baseline Age < 11 yr
Baseline Age > 11 yr
