Figure 4.

Bland-Altman plot for the extravascular lung water index (EVLWI) measured using transpulmonary single thermodilution (EVLWI_ST) and postmortem gravimetry (EVLWI_G) in sheep. The x-axis shows the mean of EVLWI measurements by single thermodilution and gravimetry. The y-axis shows the difference between the methods. The bold line indicates the value for the mean difference between EVLWI_ST and EVLWI_G (bias), and each dashed line indicates two standard deviations (SDs). Mean difference EVLWI_ST - EVLWI_G = 4.91 ml/kg (SD 2.54 ml/kg).
