Table 3 Estimated survival status of patients with different combinations of intraoperative hyper−/hypotension

Conditions	N	Mean overall survival in months (95% CI)	1-yr survival rate in % (95% CI) ^a	3-yr survival rate in % (95% CI) ^a	5-yr survival rate in % (95% CI) ^a
Intraoperative hypertension (+), hypotension (−) ^b	167	76.9 (70.6–83.2)	89.8 (85.3–94.3)	76.6 (70.1–83.1)	66.5 (59.2–73.8)
Intraoperative hypertension (+), hypotension (+) ^b	119	72.1 (64.8–79.4)	92.4 (87.7–97.1)	73.1 (65.1–81.1)	61.3 (52.5–70.1)
Intraoperative hypertension (−), hypotension (−) ^b	69	65.6 (57.1–74.1)	89.9 (82.8–97.0)	72.5 (61.9–83.1)	56.5 (44.7–68.3)
Intraoperative hypertension (−), hypotension (+) ^b	160	58.3 (51.9–64.7)	85.6 (80.1–91.1)	55.6 (48.0–63.2)	41.2 (33.6–48.8)

Data are mean duration of overall survival in months or survival rate in % (95% CI)
Abbreviations: N number of patients with events, CI confidence interval
^a Estimated with Kaplan-Meier analyses
^b Intraoperative hypertension was defined as a systolic blood pressure > 140 mmHg for ≥5 min; intraoperative hypotension was defined as a systolic blood pressure < 100 mmHg for ≥5 min
