Table 1. Mean age at the start of therapy ± SD (in brackets: number of patients).

	GHD total (139)
Not a CrescNet partner	9.50 ± 3.78 (44)
	p = 0.26
CrescNet partner	8.77 ± 3.40 (95)
Patients without screening	9.28 ± 3.39 (65)
	p = 0.031
Patients after screening	7.67 ± 3.21 (30)

The patients from non-CrescNet partners began therapy later than those from CrescNet partners. The age at which therapy was started for patients detected by screening from practices of CrescNet partners was significantly lower than that of patients not detected by screening.
