Control Subjects MPHD Patients Control Subjects MPHD Patients Fig.1 Individual peak serum GH concentrations in control subjects and in patients with MPHD for: A, ITT, B, ARG-GHRH; C, ARG-L-Dopa; D, ARG; and E, L-Dopa. Panel F depicts serum IGF-1 concentrations measured at the screening visit in the two groups. The median peak GH or IGF-1 level in each groups denoted with a bar. The upper right box in each stimulation test panel shows the time course of the mean GH response in the two groups. The dashed lines and superscripts indicate diagnostic cut-points that can be employed as follows: a, minimize misclassification of MPHD patients and control subjects; b, 95% sensitivity for GHD; and c, 95% specificity for GHD A.
