Mean increase in hemoglobin (Hb) from the lowest in-hospital Hb value to hospital discharge and to the follow-up visit in (a) all FCM-treated patients, (b) patients aged older than or equal to 75 years, (c) patients with Charlson Comorbidity Index of at least 3, and (d) patients with Hb of up to 10 g/dl at hospital admission. Values are shown at the time of hospital admission, the lowest Hb value recorded during hospitalization (before treatment administration), at the time of hospital discharge, and at follow-up. Numbers in brackets indicate SD. P values are based on the paired t-test. FCM, ferric carboxymaltose.
