Comparison of the cycle threshold values of Liat with those of other molecular assays using the same samples. a Liat vs. cobas E-gene in nasal samples; b Liat vs. cobas ORF1a/b in nasal samples; c Liat vs. NIID in nasal samples; d Liat vs. NIID in nasopharygeal samples. The lines and surrounding gray areas indicate linear regression lines with 95% confidence intervals. The blue circles are samples for which both molecular assays tested positive. The light blue circles are samples for which one assay was positive and the other was negative. cobas cobas 6800 system and cobas SARS-CoV-2 & Influenza A/B (cobas); Ct cycle threshold; Liat cobas Liat system and cobas Liat SARS-CoV-2 & Influenza A/B; NIID national standard method developed by the National Institute of Infectious Diseases of Japan
