Multivariate regression was performed after the correlation study, showing that GH as well as IGF1 values, adjusted for Tanner’s stage, sex and BMI, were negatively associated with HOMA-IR but above all with liver fibrosis (GH:→β = −2.3, SE 0.31, p = 0.001; IGF1:→β = −2.8, SE = 1.1, p = 0.001). The gene discussed is IGF1; the disease is Hepatic fibrosis.
