According to univariate logistic regression, the odds of a severe COVID-19 diagnosis were 2.62 and 2.58 times higher in patients with a high IP-10 and TNF-α concentration at T0 compared to patients with a low concentration (p = 0.240 and p = 0.239; Table 3a,b), respectively. This evidence concerns the gene CXCL10 and COVID-19.
