Figure 3
Normalized Bland-Altman plot of the agreement between Ees and arterial dP/dt max . Average = (Ees° + arterial dP/dtmax°)/2 and difference = Ees° - arterial dP/dtmax° where X° is the normalized value of X [X° = (value of X - mean of X)/standard deviation of X]. Lines represent mean difference (solid lines) and 95% confidence interval (light dashed line) (PPV ≤ 11%).
