Progression-free survival. Progression-free survival was defined as the time from date of randomization to the earlier of disease progression or death due to any cause. Vertical tick marks represent the progression-free survival time of patients without disease progression. Hazard ratio (CVac/SOC) was estimated using a Cox proportional hazards model. P-value was calculated using the log-rank test. a Progression-free survival for patients in complete remission after first-line therapy; CR1. b Progression-free survival for patients in complete remission after second-line therapy; CR2
