Relationship between SARS-CoV-2 RNA load in the lower respiratory tract and peripheral blood levels of SARS-CoV-2 S1/M-reactive IFN-γ T cells. SARS-CoV-2 RNA load in tracheal aspirates in patients with or without concurrent detection of peripheral blood SARS-CoV-2 S1/M-reactive IFN-γ CD8+ (A) or CD4+ (B) T cells and SARS-CoV-2 S1/M-reactive IFN-γ CD8+ (C) or CD4+ (D) T-cell levels in peripheral blood according to the presence or absence of detectable SARS-CoV-2 RNA in paired tracheal aspirates. Bars represent medians and 95% CI values. P values for comparisons are shown.
