On the contrary, a statistically significant negative correlation (FDR < 0.05) was observed for Sutterella and 12 proteins (CXCL1, CCL20, DCTN1, CXCL5, GLB1, ZBTB16, PRDX3, TGF-B1, CXCL1, MMP-1, AXIN1, and CXCL10), mostly involved in enhancement of inflammatory processes, for both “mild” and “asymptomatic” disease groups, as well as for the for the entire COVID-19 cohort. This evidence concerns the gene CXCL5 and COVID-19.
