Bland-Altman plots. (a, b) Bland-Altman plot for the changes (in absolute values) and correlation (for the percentage changes) induced by volume expansion on cardiac index obtained by transpulmonary thermodilution (CItd) and cardiac index obtained by the pulse-contour analysis (CIpc). (c, d) Bland-Altman plot for the changes (in absolute values) and correlation (for the percentage changes) induced by volume expansion on cardiac index obtained by transpulmonary thermodilution (CItd) and cardiac index obtained by the arterial pressure waveform analysis (CIpw). Bland-Altman plots: straight line, bias; dashed line: +2 SD/-2 SD limits of agreement); dashed line, correlation line.
