Fig. 3From: A prospective observational study of iron isomaltoside in haemodialysis patients with chronic kidney disease treated for iron deficiency (DINO)Mean Hb changes for the IIM prospective phases versus the IS retrospective phase. Non-inferiority was achieved for the primary endpoint comparison of IIM 0–3 months to IS where the lower limit of the 95% CI was above the margin of − 0.15 g/dL. CI = confidence interval; Hb = haemoglobin; IIM = iron isomaltoside; IS = iron sucroseBack to article page
