Regardless of the mean CTL-S as a continuous variable in model 1 or the presence of hepatic steatosis as a binary variable in model 2, mean CTL-S (OR 1.087, 95% CI 1.018–1.161, p = 0.013) or absence of hepatic steatosis (OR 0.159, 95% CI 0.031–0.814, p = 0.027), and mean psoas muscle HU were independent factors for elevated AFP levels. The gene discussed is AFP; the disease is fatty liver disease.
