Table 4 Comparison of blood pressure using the Bland-Altman method

From: Accuracy of invasive arterial pressure monitoring in cardiovascular patients: an observational study

  Bias, mmHg Limits of agreement, mmHg
R-group systolic IBP versus systolic NIBP 28.5 −2.92 to 59.58
NR-group systolic IBP versus systolic NIBP 4.1 −6.19 to 14.40
R-group diastolic IBP versus diastolic NIBP −2.2 −23.42 to 14.81
NR-group diastolic IBP versus diastolic NIBP −1.1 −12.5 to 10.3
R-group mean IBP versus mean NIBP 7.4 −14.98 to 29.50
NR-group mean IBP versus mean NIBP 2.3 −13.09 to 17.69
  1. R-group, resonance group; NR-group, non-resonance group; IBP, invasive blood pressure monitoring; NIBP, non-invasive blood pressure monitoring.
