Deming regression fit for VTM diluted samples for both targets in RT-PCR N1 and N2. Each dot shows Ct values for SoC RT-PCR (x-axis) and Novel RT-PCR (y-axis) for one sample. Colors represent the IDs of the five patients. The solid line represents the Deming regression line with the 90% confidence interval of the bias between both methods (shaded area). The dashed lines represent the identity line and interval of ± 3 Ct around it. This Ct interval is considered as acceptable.
