Fig. 2From: The relationship between preoperative blood pressure during anesthetic examinations and pre-intubation blood pressureCorrelation between pre-examination systolic BP and pre-intubation systolic BP (a) (r = 0.4673, p < 0.0001, 95% CI = 0.3415 to 0.5767) and Bland–Altman plots between pre-examination systolic BP and pre-intubation systolic BP (b) (mean bias ± SD = 10.2 ± 20.5 mmHg, 95% LOA = -30.0 to + 50.4 mmHg)Back to article page
