From: Association of perioperative blood pressure with long-term survival in rectal cancer patients
Kaplan–Meier survival curves of rectal cancer patients with different preoperative and postoperative BPs. The curves showed significantly lower DFS (a) and CSS (b) rates in the high-preoperative SBP group than in the low-preoperative SBP group. Patients in the high-postoperative SBP group had significantly lower CSS (d) rates, whereas the differences in the DFS curves (c) were not significant.
