Elevated serum inflammatory cytokines normalize after recovery from SARS-CoV-2 infection. a–c Left Panel: Serum levels of (a) IL-6, (b) IL-8 and (c) IL-10 in healthy donors (HD) and SARS-CoV-2 patients (CoV-2). Middle bars represent medians. Full red symbols indicate deceased patients. The Mann–Whitney U test was used to compare the two groups. a–c Right panel: Serum levels of (a) IL-6, (b) IL-8 and (c) IL-10 in the acute phase and after recovery. Paired data were analyzed by the Wilcoxon signed rank test. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. d, e Correlation of IL-6 with LDH and CRP. f, g Correlation of IL-10 with LDH and PCR. The Pearson test was used to examine correlations
