Linear regression of blood pressure to blood loss in mastectomies. MBP mean blood pressure, SBP systolic blood pressure. a In partial mastectomy, systolic blood pressure (SBP) was positively correlated with blood loss in the non-remifentanil group. b Mean blood pressure (MBP) was not correlated with blood loss. c In quadrantectomy, SBP tended to be positively correlated with blood loss in the non-remifentanil group. d MBP was positively correlated with blood loss in the non-remifentanil group
