Duration of response (DoR). Thirty-one of the 33 patients eligible for maintenance started maintenance after induction. A total of 9 events (progressions, n = 8; deaths from any cause, n = 1); 2-year DoR, 63.8% (95% CI, 40.6-79.9), median not reached. The blue solid line represents the DoR probability according to the Kaplan-Meier (KM) method and the red dashed line the 95% confidence interval (95CI).
