GH1 and obesity due to melanocortin 4 receptor deficiency: The lowest quartile group (Q1) (peak GH response to GHRP-2 < 5.04 ng/mL) (exp [β] = 2.257; 95% CI, 1.646 to 3.094) was significantly associated with an increase in serum hs-CRP levels compared with the highest quartile group (Q4) (peak GH response to GHRP-2 ≥ 34.75 ng/mL) after adjusting for age, sex, obesity, hypertension, diabetes mellitus, dyslipidemia, and serum creatinine level (model 1) (Fig. 4).
