OS by best overall response in patients in the (A) nivolumab plus ipilimumab, (B) nivolumab, or (C) ipilimumab groups. Patients with a best overall response of CR, PR, SD, or PD within 12 months of treatment initiation were followed for OS. To address guarantee-time bias, these landmark analyses excluded patients who had OS events (deaths) during the first 12 months; thus, OS remained at 100% for the first 12 months in this subpopulation. CR, complete response; OS, overall survival; PD, progressive disease; PR, partial response; SD, stable disease.
