Kaplan-Meier survival curves according to the amount of intraoperative blood loss (IBL) for patients undergoing lobectomy at various pathologic (p-) stages. (A) p-IA, (B) p-IB, (C) p-IIA, (D) p-IIB, (E) p-IIIA, (F) p-IIIB, and (G) p-IV. In each instance, the median amount of IBL was used as the cut off value between equal size groups. Significance was found in p-stage IB to IIIB but not in p-stages IA and IV.
