Study dose versus calculated iron need for anaemic patients.

Anaemic patients^a	IBD CD; ()	IBD UC; ()	Non-IBD; ()	Total; ()
Mean (SD)
Study dose^b, mg	1058 (338.1)	1115 (265.6)	1115 (305.6)	1100 (306.2)
Iron need calculated from simplified dosing table, mg	1420 (325.1)	1438 (324.0)	1532 (316.3)	1481 (322.9)
Iron need calculated from Ganzoni formula^c, mg	1268 (279.4)	1261 (316.0)	1380 (284.1)	1324 (294.2)

^aAnaemia defined as Hb < 13 g/dL for men and Hb < 12 g/dL for women at baseline. Patients having a weight < 50 kg and patients with missing weight data were excluded. ^bStudy dose for first iron isomaltoside treatment. ^cGanzoni formula based on a target Hb of 15 g/dL, Hb level before first iron isomaltoside treatment in study, and iron store of 500 mg. CD: Crohn’s disease; Hb: haemoglobin; IBD: inflammatory bowel disease; SD: standard deviation; UC: ulcerative colitis.
