Bland–Altman analysis of CVP and EJVP absolute values. In the supine position, mean bias was −0.3 mm Hg with limits of agreement (as represented by ±2 sd) and 95% confidence intervals of −2.6 (−2.9 to −2.2) to +1.9 (+1.6 to +2.2) mm Hg (a). In the lateral position, mean bias was −1.2 mm Hg with limits of agreement (95% CI) from −5.8 (−6.8 to −4.5) to +3.8 (+2.7 to +4.9) mm Hg (b).

3. Fig 2
Bland–Altman analysis of changes in CVP and EJVP (ΔCVP and ΔEJVP, respectively) over time or in response to fluid boluses. In the supine position, mean bias was 0 mm Hg with limits of agreement (95% CI) from −2.3 (−2.8 to −1.8) to +2.3 (+1.7 to +2.8) mm Hg (a). In the lateral position, the mean bias was −0.1 mm Hg with limits of agreement (95% CI) from −3.0 (−3.7 to −2.3) to +2.9 (+2.2 to +3.5) mm Hg (b).
