Table 6 SDres results for children born preterm, giving the first and second year response. Model group (left) and total Validation group (right). SDstandRes gives the ratio SDres/SDresModelgroup, 2*cm 3 y gives the 2 SD prediction interval in cm at 3 years of age and 2*cm 7 y gives this interval at 7 years of age.

From: Models predicting the growth response to growth hormone treatment in short children independent of GH status, birth size and gestational age
