Study Arms:
- Intravenous ferric carboxymaltose (Type: ACTIVE_COMPARATOR): Ferric Carboxymaltose solution \[Ferinject® (FCM), Vifor Pharma (Glattbrugg, Switzerland)\] will be given as a perfusion of 20 mL (which is the amount of FCM that is equivalent to 1000 mg of iron) diluted in a sterile saline solution (0.9% weight/volume (w/v) NaCl) administered over at least 15 min.
- Normal saline (Type: PLACEBO_COMPARATOR): Normal saline (0.9% weight/volume (w/v) NaCl) administered as per the instructions for active therapy.

Based on this trial design, predict the completion outcome and termination type (if applicable).
