Interarm SBP differences appear similar across ages; leaves open whether higher rates exceeding 10 mmHg in elderly warrant age-specific thresholds.
Does age affect the magnitude of simultaneous interarm blood pressure differences?
Clinically important interarm blood pressure differences exist across age groups, reinforcing the need to measure blood pressure in both arms during initial clinical assessments to prevent misclassification.
Fotherby et al. (1993) studied this question.
