Bland-Altman Analysis of Stroke Volume Measurements with and without Phantom Correction. Scatter plots show the mean stroke volume compared to the difference in stroke volume for measurements with and without phantom correction. Each plot represents a single patient. The plots include patients across all three diagnostic groups. The solid horizontal line represents the mean of the differences in SV, while the dotted lines represent 2 standard deviations of that mean in each direction. RVOT = Right ventricular outflow tract. pOff-pOn = SV measured without phantom correction minus SV measured with phantom correction.
