Bland–Altman plots presenting the mean and the difference in blood pressure measurements (mmHg) between the wrist and arm monitors over 24 hours for SBP (a) and DBP (b). The solid black horizontal line represents the mean difference and the dotted horizontal lines represent 2SD above and below the mean. There was a mean difference of +0.7 mmHg and a 2SD difference between the arm monitor and the wrist monitor of -37.7 to 39.1 mmHg for SBP and a mean difference of -3.9 mmHg and a 2SD difference of -30.9 to 23.1 mmHg for DBP. DBP = diastolic blood pressure, SBP = systolic blood pressure.
