Additional file 1 of Resource-efficient internally controlled in-house real-time PCR detection of SARS-CoV-2

Additional file 1: Figure S1. Correlation of the CT values obtained for 407 specimens positive for the E-Gene PCR with the orf1ab PCR. Shown is the correlation over all specimens (blue line, R2 = 0.94), for specimens with E-Gene PCR CT values below CT = 33 (red line, R2 = 0.95) and for specimens with E-Gene PCR CT values above CT = 33 (green line, R2 = 0.33).
