Fig. 3From: The relationship between preoperative blood pressure during anesthetic examinations and pre-intubation blood pressureCorrelation between intra-examination systolic BP and pre-intubation systolic BP (a) (r = 0.5230, p < 0.0001, 95% CI = 0.4050 to 0.6238) and Bland–Altman plots between intra-examination systolic BP and pre-intubation systolic BP (b) (mean bias ± SD = 2.2 ± 18.3 mmHg, 95% LOA = -33.7 to + 38.1 mmHg)Back to article page
