Four‐limb blood pressures and their differences

Variables	Mean ± SD/Median (IQR) or n (%)
Right arm systolic BP, mm Hg	145 ± 22
Right arm diastolic BP, mm Hg	80 ± 12
Left arm systolic BP, mm Hg	143 ± 21
Left arm diastolic BP, mm Hg	79 ± 11
Right leg systolic BP, mm Hg	156 ± 24
Right leg diastolic BP, mm Hg	75 ± 10
Left leg systolic BP, mm Hg	154 ± 24
Left leg diastolic BP, mm Hg	75 ± 10
IASBPD, mm Hg	5 (2‐10)
ILSBPD, mm Hg	7 (3‐13)
ABI	1.0 ± 0.1
IASBPD ≥10 mm Hg, n (%)	635 (24.2)
IASBPD ≥15 mm Hg, n (%)	482 (18.4)

Values are represented as n (%) or mean ± SD/median (IQR).

Abbreviations: ABI, ankle‐brachial index; BP, blood pressure; IASBPD, inter‐arm systolic blood pressure difference; ILSBPD, inter‐leg systolic blood pressure difference; IQR, interquartile range.
