Plasma concentration of inflammatory cytokine/chemokine levels in COVID-19 patients who received favipiravir with or without minocycline. Sample size was 6 for the MIN group and 5 for the control group. Horizontal bars represent median values. Statistical significance was only tested between values on admission (acute) and before discharge (convalescent) in the Control group and MIN group. However, for IFN-γ, IL-6, and IL-8, only the MIN group was tested because they were clearly elevated in the convalescent phase in the control group. *Values of P < 0.05 were deemed significant. IFN-γ, interferon-gamma; IL, interleukin; MIN, minocycline; TNF-α, tumor necrosis factor alpha.
