Fig. 4From: The relationship between preoperative blood pressure during anesthetic examinations and pre-intubation blood pressureCorrelation between post-examination systolic BP and pre-intubation systolic BP (a) (r = 0.4980, p < 0.0001, 95% CI = 0.3764 to 0.6028) and Bland–Altman plots between post-examination systolic BP and pre-intubation systolic BP (b) (mean bias ± SD = 15.3 ± 19.5 mmHg, 95% LOA = -22.9 to + 53.6 mmHg)Back to article page
