In the logistic regression analysis IL-18 (OR-1.006, 95% CI for OR—1.001–1.010, and p = 0.018) and triglycerides (OR-1.015, 95% CI for OR—1.003–1.028, and p = 0.012) were the only measures useful in the differentiation of obese patients with liver steatosis confirmed using 1HMRS. Here, IL18 is linked to fatty liver disease.
