Comparability of PD-L1 scoring between the four standardized PD-L1 assays. Comparison of the a tumor proportion score (TPS) and b combined positive score (CPS) for the four PD-L1 assays. Frequencies distributions for the c tumor proportion score and d combined positive score at different cutoffs. e Inter-assay agreement among different PD-L1 assays of the tumor proportion score and combined positive score at different cutoffs. f Proportion of correctly classified positive samples and negative samples by any one assay (28–8, SP142 and SP263) in comparison with the 22C3 assay
