  1. a → Dependent variable: AOP. Five parameters (systolic blood pressure, diastolic blood pressure, upper extremity circumference, arterial diameter and blood flow velocity) entered into stepwise regression procedure as independent variables and the upper extremity circumference (X1) and SBP (X2) were found as the best predictors, which were highly correlated with the dependent variable AOP.
