Panel A shows progression‑free survival among patients who received RVD alone and among those who received RVD plus transplantation. In the RVD‑alone group, of 189 events of disease progression or death, 1 death occurred in the absence of disease progression. In the transplantation group, of 139 events, 11 deaths occurred in the absence of disease progression. Panel B shows the Kaplan–Meier analysis of overall survival in the two groups; there were 90 deaths in the RVD‑alone group and 88 deaths in the transplantation group. In both panels, tick marks indicate censored data.
