results We performed multivariate forward analysis to determine the factors associated with an interankle SBP difference ≥ 15 mm Hg. An ABI < 0.9 (P < 0.001), high baPWV (P < 0.001), and increased left ventricular mass index (LVMI; P = 0.004) were associated with an interankle SBP difference ≥ 15 mm Hg. Also, the addition of an interankle SBP difference ≥ 15 mm Hg to a model of clinical features could significantly improve the value in predicting ABI < 0.9 (P < 0.001) and increased LVMI (P = 0.036).
