Data are presented as standardized hazard ratio (i.e. per unit SD) to permit direct comparisons. All data are adjusted for age and sex. Abbreviations: AIx – augmentation index, AIx75 heart rate corrected augmentation index, AP – augmentation pressure, bSBP – brachial systolic blood pressure, cPP – central pulse pressure, cSBP – systolic blood pressure, DBP – diastolic blood pressure, Pres – reservoir pressure, PRI – reservoir pressure intergral, XSPI – excess pressure integral.
