Results are presented as the aMD for each hemodynamic measure between women with preeclampsia and controls, after adjustment for confounders in the multivariable model. The reported P value refers to the comparison of each hemodynamic measure between the two groups. AIx indicates augmentation index; aMD, adjusted mean difference; cfPWV, carotid‐femoral pulse wave velocity; DBP, diastolic blood pressure; GRC, global reflection coefficient; MAP, mean arterial pressure; PAC, proximal aortic compliance; Pb, reflected pressure wave amplitude; Pf, forward pressure wave amplitude; PP, pulse pressure; SBP, systolic blood pressure; SVR, systemic vascular resistance; TAC, total arterial compliance; and Zc, aortic characteristic impedance.
