Association between serum hs-CRP levels and GH secretion. Forest plot demonstrating exponential transformation of β coefficients (exp [β]) and 95% CIs of quartiles of peak GH response to GHRP-2 levels in the multivariable regression analyses to estimate serum hs-CRP levels, with the highest quartile (Q4) as reference. Because the dependent variable was log-transformed, the β coefficients were exponentially transformed. Exponential transformation of β coefficients (Exp [β]) implies an interpretation on a multiplicative scale. Exp (β) implies an interpretation on a multiplicative scale. The serum hs-CRP level changes by 100 × (exp [β])% in the quartiles of peak GH response to GHRP-2 levels compared with Q4. Model 1: adjusted for age, sex, obesity, hypertension, diabetes mellitus, dyslipidemia, and creatinine level. Model 2: adjusted for factors used in model 1 + corticotroph deficiency, thyroid function, and hypogonadotropic hypogonadism. Model 3: Adjusted for the factors used in model 2 + elevated liver enzymes. Abbreviations: GHRP, GH-releasing peptide; hs-CRP, high-sensitivity C-reactive protein.
