Finally, we studied logistic regression models for steatosis (CAP ≥300 db/m) and fibrosis (hepatic stiffness ≥7.1 kPa) using forward conditional analysis on putative determinants at p<0.1 in univariate analysis (use of PIs, BMI, ALT, AST, GGT, bilirubin, HBA1c) and the SNPs, respectively. The gene discussed is GPT; the disease is fibrosis.
