Higher Arm Versus Lower Arm Systolic Blood Pressure and Cardiovascular Outcomes : a Meta-Analysis of Individual Participant Data From the INTERPRESS-IPD Collaboration
BACKGROUND: Guidelines recommend measuring blood pressure (BP) in both arms, adopting the higher arm readings for diagnosis and management. Data to support this recommendation are lacking. We evaluated associations of higher and lower arm systolic BPs with diagnostic and treatment thresholds, and prognosis in hypertension, using data from the Inter-arm Blood Pressure Difference - Individual Partic
