Evolution of hemoglobin levels (g/dL) at four time points: diagnosis, hospital admission, discharge, and 30 days post-surgery. Groups were not censored for transfusions. Significant differences between groups are marked with an asterisk for Hb and dagger for serum ferritin (*p < 0.05; **^/† p < 0.005; ***^/‡ p < 0.001). Ferric carboxymaltose (FCM) was administered during diagnosis period
