Receiver operator characteristic (ROC) analyses were performed using five sets of NSCLC patient tumors with two different PD-L1 IHC TPS cutoff groups in each set: IHC high versus negative (Figure 2A); IHC low versus negative (Figure 2B); IHC high versus low (Figure 2C); IHC high + low versus negative (Figure 2D); and IHC high (TPS ≥ 50) versus low + negative (Figure 2E). The gene discussed is CD274; the disease is non-small cell lung carcinoma.
