Scatterplots of vascularization index, flow index and vascularizationflow index versus gestational age. Curve regression lines indicate the mean values. VI = exp. (4.369–28.533/GA) (R2 = 0.699, p < 0.05); FI = exp. (3.916–13.003/GA) (R2 = 0.511, p < 0.05); VFI = exp. (3.577–37.468/GA) (R2 = 0.675, p < 0.05). GA, Gestational age; FI, Flow index; VFI, Vascularizationflow index; VI, Vascularization index
