In female participants, the prevalence of NAFLD was related to age (OR = 1.067, p < 0.05), BMI (OR = 1.472, p < 0.001), having PPD ≥ 4 mm (OR = 2.972, p < 0.05), total cholesterol concentration (OR = 0.902, p < 0.01), triglyceride concentration (OR = 1.025, p < 0.01), HDL cholesterol concentration (OR = 1.103, p < 0.05), and CRP concentration (OR = 8.736, p < 0.05). The gene discussed is CRP; the disease is metabolic dysfunction-associated steatotic liver disease.
