Correlation and Bland-Altman agreement analysis of four cross-regional perfusion distributions and V/Q match between hypertonic sodium saline and sodium bicarbonate. 2A, Scatter plot of regional lung perfusion (% of total perfusion) between indicators. Correlation defined by R2 is shown overall and within each lung region. 2B, Bland–Altman plot of regional lung perfusion (% of total perfusion) by lung region between indicators. 2C, Scatter plot of regional V/Q match (%) between indicators. 2D, Bland–Altman plot of r regional V/Q match (%) between indicators. LOA, limits of agreement
