  1. Total operative time was determined from the start of anesthesia to the end of anesthesia
  2. Procedure time was determined from the start time of the surgical incision to the end of the suture
  3. Postoperative Hb drop was calculated as preoperative Hb level– postoperative Hb level
  4. Postoperative day 1 Hb drop was calculated as preoperative Hb level– postoperative day 1 Hb level
  5. Hb, hemoglobin
