The July 1, 2019, article by Sharma et al, entitled “Nivolumab Alone and With Ipilimumab in Previously Treated Metastatic Urothelial Carcinoma: CheckMate 032 Nivolumab 1 mg/kg Plus Ipilimumab 3 mg/kg Expansion Cohort Results” (J Clin Oncol 10.1200/JCO.19.00538), was published with an error.
In Figure A1A in the appendix, the green column at the far right was labeled n = 42. It should have been n = 31.
