Conclusions: The toe brachial index demonstrates limited associations with physical and social aspects of health-related quality of life in older people.]]> Wed 11 Apr 2018 09:33:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26892 Sat 24 Mar 2018 07:41:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32590  50% arterial obstruction was identified in any lower limb vessel using colour duplex ultrasonography. A receiver operating characteristic curve was analysed and the sensitivity and specificity of commonly used toe brachial index and toe blood pressure values were determined. Results: The optimum toe brachial index threshold value for diagnosing peripheral arterial disease was 0.72 (sensitivity 76.2%, specificity 75%). The area under the curve was 0.829 (95% CI 0.743 to 0.915, p < 0.0001) suggesting fair diagnostic accuracy. A toe blood pressure of 70 mmHg was found to have excellent specificity (97.92%) for detecting PAD but poor sensitivity (42.86%). Conclusions: The accuracy of automated toe blood pressure and TBI measurements was determined to be good when using colour duplex ultrasound as the reference standard for the non-invasive diagnosis of peripheral arterial disease. Results should be interpreted in the context of all clinical signs and symptoms.]]> Fri 01 Apr 2022 09:24:40 AEDT ]]>
