Abstract

PURPOSE

Variability of ankle brachial index (ABI) measured by the same observer in the same individual on three different occasions was examined.

BASIC METHODS

A single morning ABI was initially determined (measurement 1) with handheld Doppler device. One to four weeks apart, another morning (measurement 2) and afternoon (measurement 3) ABI was measured on the same day.

PRINCIPAL FINDINGS

A total of 161 adults were enrolled. Mean ABI was similar among the three measurements. ABI differed more than ≥0.15 in 15 individuals between measurement 1 and 3, in 10 subjects between measurement 1 and 2, and in 12 individuals between measurement 2 and 3. Intra-group correlation coefficients of reproducibility of ABI were 0.808 for single measurements (coefficient of the values lacking association with each other), and 0.927 for average measurements (coefficient of the values that were associated with each other).

CONCLUSIONS

Although reproducibility of ABI values was found satisfactory, up to 12% of participants displayed more than 0.15 alternations between measurements, either on the same day or more than a week apart.

摘要

目的

研究同一观察者在三个不同时间点对同一个体测量踝臂指数（ABI）的变异性。

基本方法

最初使用手持式多普勒设备在一个早晨测定一次ABI（测量1）。在相隔1至4周的同一天，在另一个早晨（测量2）和下午（测量3）测量ABI。

主要发现

共纳入161名成年人。三次测量的平均ABI相似。在测量1和3之间，15名个体的ABI差异超过≥0.15；在测量1和2之间，10名受试者的ABI差异超过≥0.15；在测量2和3之间，12名个体的ABI差异超过≥0.15。ABI重复性的组内相关系数，单次测量为0.808（相互无关联值的系数），平均测量为0.927（相互有关联值的系数）。
