Analytical comparison of tumor and immune cell staining for the four PD-L1 diagnostic assays. Distribution of the tumor cell proportion score (a) and immune cell proportion score (by tumor area, b) for each assay were plotted by case. For a better illustration of the association among the four assays, the first 300 cases with low tumor cell score and first 400 cases with low immune cell score (<1%) were removed from the plots
