Fig. 3From: Concordance among four commercially available, validated programmed cell death ligand-1 assays in urothelial carcinomaPercentage of PD-L1–positive TC and IC (per IC area) ranked by average value. Exponential fits to the data are provided for ease of visualization. a % of TC membrane staining ranked by average % of TC membrane staining. b % of IC membrane staining ranked by average % of IC membrane staining.
