Relative change in iron-related blood parameters in the 4 weeks following surgery in the iron group compared to the control group, assessed using a linear mixed model.

Parameter	PGroup×Time
Haemoglobin (g/dL)	0.102
Reticulocyte count (103/$\mu$L)	0.002
Reticulocyte production index (%)	0.002
Iron ($\mu$g/dL)	< 0.001
Ferritin (μ/L)	< 0.001
Transferrin saturation (%)	< 0.001
TIBC ($\mu$g/dL)	< 0.001
Transferrin (mg/dL)	< 0.001
