The two groups statistically differ in BMI (p < 0.001), NLR (p < 0.001), glucose (p < 0.001), triglycerides (p < 0.001), ALT (p = 0.027), and GGT (p < 0.001), which were statistically higher in the COVID-19 group than controls, while hemoglobin (p = 0.041), albumin (p < 0.001), total cholesterol, HDL (p < 0.001), and LDL (p < 0.001) (p < 0.001) were statistically lower. This evidence concerns the gene GPT and COVID-19.
