GH1 and metabolic syndrome: In the multiple linear regression analysis (Table 3), the peak GH response to GHRP-2 (β = −0.376; 95% CI, −0.511 to −0.240; standardized β = −0.413) was a significant variable for determining serum hs-CRP levels after adjusting for age, sex, hypertension, diabetes mellitus, dyslipidemia, and serum creatinine level (model 1).
