  abstract = {{S}ystolic interarm differences in blood pressure have been associated with all-cause mortality and cardiovascular disease. {W}e undertook individual participant data meta-analyses to (1) quantify independent associations of systolic interarm difference with mortality and cardiovascular events; (2) develop and validate prognostic models incorporating interarm difference, and (3) determine whether interarm difference remains associated with risk after adjustment for common cardiovascular risk scores. {W}e searched for studies recording bilateral blood pressure and outcomes, established agreements with collaborating authors, and created a single international dataset: the {I}nter-arm {B}lood {P}ressure {D}ifference - {I}ndividual {P}articipant {D}ata ({INTERPRESS}-{IPD}) {C}ollaboration. {D}ata were merged from 24 studies (53 827 participants). {S}ystolic interarm difference was associated with all-cause and cardiovascular mortality: continuous hazard ratios 1.05 (95% {CI}, 1.02-1.08) and 1.06 (95% {CI}, 1.02-1.11), respectively, per 5 mm {H}g systolic interarm difference. {H}azard ratios for all-cause mortality increased with interarm difference magnitude from a 5 mm {H}g threshold (hazard ratio, 1.07 [95% {CI}, 1.01-1.14]). {S}ystolic interarm differences per 5 mm {H}g were associated with cardiovascular events in people without preexisting disease, after adjustment for {A}therosclerotic {C}ardiovascular {D}isease (hazard ratio, 1.04 [95% {CI}, 1.00-1.08]), {F}ramingham (hazard ratio, 1.04 [95% {CI}, 1.01-1.08]), or {QRISK} cardiovascular disease risk algorithm version 2 ({QRISK}2) (hazard ratio, 1.12 [95% {CI}, 1.06-1.18]) cardiovascular risk scores. {O}ur findings confirm that systolic interarm difference is associated with increased all-cause mortality, cardiovascular mortality, and cardiovascular events. {B}lood pressure should be measured in both arms during cardiovascular assessment. {A} systolic interarm difference of 10 mm {H}g is proposed as the upper limit of normal.},
