Relationships between the sensitivities of RDTs vs. rRT-PCR cycle threshold (Ct) values. The solid lines indicate sensitivities, the dotted lines represent the upper, and the lower bounds the corresponding 95% confidence intervals. (A) left: Roche-RDT; right: Abbott-RDT. (B) Sensitivities according to SARS-CoV-2 genotypes. left: Roche-RDT; right: Abbott-RDT; red: NIM genotype; blue: SARS-CoV-2 Alpha variant.
