Based on a subgroup analysis, improvement in event-free survival (EFS) with the KEYTRUDA-based regimen was consistent across all PD-L1 expression subgroups, histology and stage
Exploratory subgroup analysis showed a reduction in EFS events with the KEYTRUDA perioperative regimen for patients with or without pathological complete response (pCR) compared with the chemotherapy-placebo regimen
