UNASSIGNED: Individuals with an abnormal @entity3681 ( @entity3681 ) are four times more likely to have a @entity1188 ( @entity1188 ), but reliability of @entity3681 in predicting the presence of these lesions has not been estimated yet. We compared two methods of calculating @entity3681 to assess their reliability in predicting SLIs. @entity64 -free Atahualpa residents aged >=    60 years underwent MRI of the brain and @entity3681 determinations. @entity1 with @entity3681 >=    1.4 were excluded. Using receiver operator characteristic curve analysis, we calculated the reliability of the traditional as well as an alternative @entity3681 method to identify individuals with @entity1188 . The traditional @entity3681 uses the higher systolic pressure of either the dorsalis pedis or the posterior tibial arteries as the numerator, whereas the alternative @entity3681 uses the lower pressure. Of the 247 @entity1 , 38 (15%) had traditional and 95 (38%) had alternative ABIs <=    0.9. Twenty-one individuals had @entity1188 . Traditional and alternative ABIs <=    0.9 identified 9 and 13 individuals with @entity1188 , respectively. The traditional @entity3681 had sensitivity of 42.9% (22.6-65.6%) and specificity of 87.2% (81.9-91.1%). The alternative @entity3681 had sensitivity of 61.9% (38.6-81%) and specificity of 63.7% (57-69.9%). The area under the curve for the predictive value of @entity1188 was 0.65 (0.54-0.76) for the traditional and 0.63 (0.52-0.74) for the alternative @entity3681 <=    0.9. The @entity3681 is moderately reliable for identifying candidates for MRI screening in studies assessing the burden of @entity1188 in older adults. The traditional @entity3681 seems to be more suitable for this purpose.
