Methods
The study was performed in the ambulatory care section of the adult emergency department (ED) of this institution. The study was presented to and waived for formal approval by the Institutional Review Board because of its simple and noninvasive nature. Before the study, each of 100 sequential random numbers from 0 to 9 was generated from a table of random numbers 8 with even being the left arm blood pressure taken first and odd being the right arm blood pressure taken first.
Each of 100 subjects
Results
A total of 100 consecutive accidental participants who agreed to the study over 1 day were enrolled. There were 49 women and 51 men with 11 left hand dominant and 89 right hand dominant individuals. The average age was 38.0 ± 11.5 years with a range from 19 to 73. The average age for the women and men was 38.4 ± 10.9 and 37.7 ± 12.2 years, respectively.
The mean left-right systolic difference was −0.59 with a 2-tailed P value of.5037 or not significant (NS). The mean left-right diastolic
Discussion
In a series of 100 known normotensive individuals who had random noninvasive blood pressure evaluations in both arms, 15% had a difference in blood pressure of greater than 10 mm Hg that was not related to gender differences or hand dominance. This value is consistent with previous studies5, 6, 7 and indicates the degree of variability present in unbiased blood pressure determinations. The average variability in systolic blood pressure determinations in this study was slightly greater than 5%,

Inter-arm Blood Pressure Difference and its Relationship with Retinal Microvascular Calibres in Young Individuals: The African-PREDICT Study
2016, Heart Lung and CirculationCitation Excerpt :Indeed Grossman et al. found that a large IASBPD is not an uncommon phenomenon in young, healthy individuals [12]. We confirmed these findings in our study where 14.3% of participants had an IASBPD ≥ 10 mmHg, which taken together suggests that increased IASBPD ≥ 10 mmHg does not necessarily indicate endothelial dysfunction, arterial stiffness or pathology of the aortic arch or subclavian arteries [35]. Although the mechanism by which bilateral BP discrepancies occur is not fully understood, possible anatomical means have been proposed [36].

2004, Journal of the American College of CardiologyCitation Excerpt :Clinicians have continued to debate what brachial SBP difference is “clinically significant.” Previous research has shown the interarm difference in individuals without known cardiovascular pathology does not favor one arm and does not vary by gender or age (4,9–12). Furthermore, in a population of subjects (n = 400) with significant cardiovascular risk factors, Lane et al. (13) employed univariate analyses to demonstrate that increased age was the only significant predictor of SBP differences of both >10 mm Hg and >20 mm Hg, while gender, ethnicity, arm circumference, handedness, hypertension, diabetes, and cardiovascular disease were not significantly predictive.
