The relationship between ketonuria and an intermediate–high probability of advanced liver fibrosis, using NFS, was not attenuated after adjusting for sex, hypertension, and obesity (Model 1: OR, 0.65; 95% CI, 0.48–0.87; p = 0.005); after further adjustment for lipid profiles (Model 2: OR, 0.65; 95% CI, 0.48–0.88; p = 0.004); after final adjustment for albumin, GGT, hsCRP, and HOMA-IR (Model 3: OR, 0.58; 95% CI, 0.40–0.84; p = 0.016) (Table 4). This evidence concerns the gene ALB and Hepatic fibrosis.
