What was measured

ORR is defined as the proportion of participants whose best overall response (BOR) is either a complete response (CR) or partial response (PR). BOR is defined as the best response designation, as determined based on BICR-assessed tumor response according to RECIST 1.1, recorded between the date of randomization and the date of first objectively documented progression or the date of subsequent anti-cancer therapy, whichever occurs first. For participants without documented progression or subsequent anti-cancer therapy, all available response designations will contribute to the BOR determination. For a BOR of CR or PR, the initial response assessment must be confirmed by a consecutive assessment no less than 4 weeks (28 days) later. Estimate of (Nivolumab - Sorafenib) is based on CMH method of weighting, stratified by stratification factors
