What was measured

NSCLC participants only: Pre-treatment levels of PD-L1 percent will be compared according to RECIST response using Wilcoxon rank-sum testing. PD-L1 percent: The percentage of tumor cells that positively express the PD-L1 protein (programmed cell death ligand 1). Tumors that express high amounts of PD-L1 (\>50%) may respond well to checkpoint inhibitors (a type of immunotherapy drug).

Analysis population: Participants in the NSCLC cohort with PD-L1 IHC evaluation. This analysis was pre-specified in the protocol to collect, analyze, and report data according to response and not by treatment Arm. Patients were classified into responders and non-responders according to RECIST criteria. PD-L1 percent was compared between these two groups of patients.

Groups in this outcome
