Summary of Passing-Bablok regression and Bland-Altman plots of Ct values obtained by our multiplex assay and commercial multiplex kit. Passing-Bablok regression and Bland-Altman plots for SARS-CoV-2 N gene (A), Influenza A M1 gene (B), Influenza B NS1 gene (C), and all genes (D). For Passing-Bablok regression plots, the dashed line indicates the ideal line, whereas the solid line shows the regression line of the distribution. For the Bland-Altman analyses, the solid line indicates the mean relative difference, and the dotted lines show the superior and inferior limits of agreement. Ct, cycle threshold
