From: Vector flow mapping analysis of left ventricular energetic performance in healthy adult volunteers
Bland–Altman plots of intra- and inter-observer variability. a Intra-observer variability in the average energy loss over one cycle (ELcycle). b Intra-observer variability in kinetic energy over one cycle (KEcycle). c Inter-observer variability for ELcycle. d inter-observer variability for KEcycle. The mean values of pairs of measurements are plotted against the difference between the measurements. The red continuous line represents the arithmetic mean and the red dotted lines represent 95% limits of agreement
