Inter-arm SBP difference was associated with higher mortality; leaves open whether routine bilateral measurement improves outcomes.
Does a between-arm difference in systolic blood pressure predict all-cause mortality in clinic patients?
Between-arm systolic blood pressure differences are reproducible and independently predict all-cause mortality, supporting the routine evaluation of BP in both arms during screening.
Agarwal et al. (2008) studied this question.
