Hierarchical summary receiver operator curves of dPCR, qPCR, and LAMP in the secondary subgroup analysis comparing the use of ORF1ab and N primer–probe sets

All studies from the clusters used pharyngeal swabs and RNA extraction and only clusters consisting of more than three studies are presented. Three clusters were identified for comparing the test performance of dPCR, qPCR, and LAMP using primers targeting the ORF1ab gene, and three were identified using primers targeting the N gene. AUC=area under the curve. dPCR=digital PCR. LAMP=loop-mediated isothermal amplification. N=nucleocapsid. ORF1ab=open reading frame 1ab. qPCR=quantitative PCR.
