For anti-inflammatory cytokines, IL-10 was significantly higher in deceased COVID-19 patients compared to patients who survived and healthy controls [Med: 9.56 pg/mL (IQR: 5.23–22.25) vs 4.56 pg/mL (IQR: 2.86–8.17) vs 2.01 pg/mL (IQR: 1.41–2.71), respectively, Kruskal–Wallis, P < 0.05] with significant pairwise differences between all groups (Fig. 1C). This evidence concerns the gene IL10 and COVID-19.
