Correlation between the changes of hemoglobin and of hematocrit. The scatter plot patterns showed that the changed value of hemoglobin and hematocrit was not clearly different between laparoscopic surgery and open surgery. , where Hb_pre is the concentration of hemoglobin one day before surgery and Hb_post is that one day after surgery. ΔHct (the changed value of hematocrit) was similarly defined. A, surgery for ovarian tumor including cystectomy and salpingo-oophorectomy (unilateral or bilateral); B, myomectomy; C, hysterectomy; L, laparoscopic surgery; O, open surgery.
