Fig 1: The laboratory parameters in healthy controls and at hospital admission of patients with COVID-19 pneumonia. The plasma concentrations of IL-6 (A), IL-8 (B), IL-10 (C), PCT (D), IFN-α (E), IFN-β (F), S100A8/A9 (G), TRAIL (H), 8-OHdG (I), were analyzed in healthy controls (n = 53) and patients with non-severe (n = 37), and severe (n = 60) COVID-19. All data were represented as means±SD. The results of different groups were compared by employing ANOVA followed by the Dunnett post hoc test. *P< 0.05, **P < 0.01, ***P< 0.001, ****P< 0.0001.
