Bold values indicate significance. BP, blood pressure; CI, confidence interval; IAD, interarm difference; OR, odds ratio; /, variables not associated with the systolic IAD cutoffs considered with a P<.10 at univariate analysis.

^aFor continuous variables OR was for a 1‐unit increase.

^bSystolic BP referred to the arm with the higher average BP reading from three consecutive automatic measurements.
