Median Time to Hb Response: Hb Increase =1 g/dL From Baseline and Hb =11 g/dL |
Median time to response was estimated using Kaplan Meier method, Cohort A and B censored at Week 17, Cohort C, D, E, and F censored at Week 25. The median number of days presented was calculated from Baseline to the day the Hb response was achieved. |
