A: Changes of perioperative platelet counts. Platelet change is calculated by subtracting platelet count on each day from the preoperative level; Pre-op indicates the day before surgery; D1, D4 and D8 indicate days 1, 4 and 8 after the procedure. *P<0.05 vs. the preoperative level in the DAPT group; #P<0.05 vs. the preoperative level in the MAPT group. B: Alterations of perioperative red blood cell counts. RBC, red blood cell; Pre-op indicates the day before the surgery; D1, D4 and D8 indicate days 1, 4 and 8 after the procedure; *P < 0.05 vs. the preoperative level in the DAPT group; #P < 0.05 vs. preoperative level in the MAPT group.
