测量误差

The cumulative distribution of the ABI measured by the two methods demonstrated that the differences among them were not homogeneously distributed across the range of ABI value. The Doppler and oscillometric ABI readings were similar below values of 0.9, at values between 0.9 and 1.16 ,the readings were nearly the same line, whereas at values exceeding 1.16, the readings were not parallel.

5多普勒法与示波法测量所得ABI值结果之差均数为0.009(95%CI -0.24～0.2)，非常接近于0，在95%可信区间之外的人数为48例(4.8%)，在误差允许范围之内，表明两者一致性较好，并且这一差值随着ABI值的增加数值逐渐减小(r=-0.09，p=0.002)。
