The average evaluation period Hb concentration for each individual was calculated using the same method, from all their available measurements taken during the evaluation period (Week 17 to Week 21). The change in Hb concentration between the baseline and evaluation periods was calculated by subtracting the baseline Hb concentration from the evaluation period Hb concentration.","dispersionType":"Standard Deviation","groups":[{"description":"Participants received MIRCERA IV injection at a starting dose based on an intermediate conversion factor from their previous ESA dose (4 \\* previous weekly epoetin dose \\[IU\\]/250 or 4 \\* previous weekly darbepoetin alfa dose \\[mcg\\]/1.1) once every 4 weeks for 20 weeks.
