1. Fig.1 Simple least-squares regression of the relationship between the log of peak GH concentration on standard GH stimulation tests and serum IGF-1 concentrations in the entire cohort of 817 patients. To convert serum IGF-1 from µg/liter to nmol/liter, multiply by 0,13

2. Number of Additional Pituitary Hormone Deficits
Fig.2 Median, 25th (first quartile, first Q) and 75th (third quartile, third Q) percentiles of peak GH concentrations on standard GH stimulation tests for each subgroup of number of additonal pituitary hormone deficiencies. The minimum (Min) and Maximum (Max) values are also plotted, but not all values are visible on this scale. The peak GH level for each group differed significantly from that observed in the other groups (P<0,05)
Peak GH differs for each group (P<0.05)
