Fig. 4.

(Left) Correlation between population averaged mean TCD PSV taken at the initial HOB=0° $(\overline{PSV})$ and population averaged mean DCS BFI also taken at the initial HOB=0° $(\overline{BFI})$. (Center) Correlation between population averaged mean TCD MV taken at the initial HOB=0° $(\overline{MV})$ and DCS $\overline{BFI}$. (Right) Correlation between population averaged mean TCD EDV taken at first HOB=0° event $(\overline{EDV})$ and DCS $\overline{BFI}$. The solid line in each plot shows the best linear fit between the two variables. Both Pearson’s and Spearman’s correlation coefficients (R² and r_s, respectively) were calculated. The R ² Pearson values are displayed for each plot.
