Non-invasive assessment of stroke volume and cardiovascular parameters based on peripheral pressure waveform
Fig 5
Bland-Altman plots comparing the stroke volume estimated by the model versus estimated using bioimpedance cardiography (PhysioFlow) for (a) control group and (b) hemodialysis patients.
Dashed horizontal lines represent the 95% limits of agreement, straight horizontal line represents the mean difference. Before plotting, the data have been logarithmically transformed. SD denotes standard deviation.
