Frequently asked questions
Turner syndrome – SDS and final height prediction: What does this calculator compute?
Classifies the height of a girl with Turner syndrome on the pooled European reference of untreated patients (Lyon 1985) and estimates the final height without growth hormone therapy – by preserving the SDS (142.9 + SDS × 6.7 cm) and with the regression SDS_final = 0.21 + 1.13 × SDS (3–12 years); for comparison, the SDS on the WHO reference.
