IL6 and COVID-19: The model suggested LDL-C (p < 0.001), HDL (p < 0.001), TC (p < 0.001), TG (p < 0.001), free T3 (p < 0.001), free T4 (p < 0.001), TSH (p < 0.001), IL-6 (p < 0.001), Procalcitonin (p < 0.001), CRP (p < 0.001), and D-dimers (p = 0.021) as independent risk factors for COVID-19 (Table 3).
