Correlation of interferon-γ-induced protein-10 (IP-10) (pg/mL) in COVID-19 patients to paired cycle threshold (C_T)-values divided by patients in the normal care unit (NCU) and intensive care unit (ICU). Group comparison of COVID-19 patients between paired C_T-values ≤30 and >30. Receiver operating characteristics curves indicating areas under the curve (AUC) for the biomarkers' detection of SARS-CoV-2 infectiousness, as assumed at C_T-values ≤30. CRP, C-reactive protein; TRAIL, tumour necrosis factor-related apoptosis-inducing ligand.
