Fig 4 Polar plot with distance from the centre as mean change in CI and Θ, the angle with horizontal axis, as agreement. ΔCI, change in cardiac index. Thick lines represent central exclusion zone (mean ΔCI<10%) and the 30° radial limits. Dashed lines show the mean polar angle (angular bias) and radial limits of agreement.
