Correlation graphs and Bland–Altman plots comparing measured and calculated PTTs. (A) Scatter plot of the calculated PTT (T-reflection/2.8) vs measured carotid to femoral transit time (cfPTT) with regression line (dashed line) for all data. (B) Bland Altman plot of T-reflection/2.8 vs cfPTT for all data. Solid line is the mean difference, and the dashed lines are ± 1.96 SD of the difference. Difference: Measured cfPTT − calculated PTT; Average: (Measured cfPTT + calculated PTT)/2.
