Global flow results. The Passing & Bablok regression scatter diagram with the regression line (solid line), the confidence interval for the regression line (dashed lines) and identity line (x = y, dotted line), for global MBF values at (A) rest (n = 12, r = 0.99) and (B) stress (n = 12, r = 0.99) for two different runs. Altman-Bland plots for rest (C) and stress (D) global myocardial blood flow, respectively.
