SBP systolic blood pressure, DBP diastolic blood pressure, PP pulse pressure
adue to missing data, complete case analysis was conducted;
bunstandardised beta, invasive SBP amplification was defined as invasive brachial SBP minus invasive aortic SBP;
cadjusted R2;
dadjusted for sex, age, height, coronary artery disease, heart rate, and mean invasive brachial arterial pressure
