Figure 1From: Predictors of the accuracy of pulse-contour cardiac index and suggestion of a calibration-index: a prospective evaluation and validation studyNotched boxplots demonstrate that bias CItd-CIpc did not increase over time and did not differ after various times to last calibration. Only if the notches of two boxplots do not overlap, this is ‘strong evidence’ that the two medians differ [31,32]. CItd: Thermodilution-derived Cardiac Index. CIpc: Pulse-contour-derived Cardiac Index. TPTD: Transpulmonary thermodilution.Back to article page
