“…Some studies, but not others, have questioned the validity of the oscillometric method for the detection of PAD. 145,155,[175][176][177] The correlation between Doppler-derived and oscillometry-determined ankle pressures and ABIs in healthy subjects or subjects with mild PAD has been acceptable in most studies 151,152,155,156,162,178 with 1 exception. 164 However, when the ABI determined by the Doppler method is in the low range, the oscillometric method results in an overestimation of the actual pressure value, 148,155,156,160,161,165,179 as illustrated in Figure 3.…”

“…These studies included 4186 subjects, most of whom had been referred to a vascular clinic, indicating that they had vascular disease and/or cardiovascular risk factors (patient characteristics in Table 2). Of the 20 devices used in these studies, 5 were designed for ABI measurements, [19][20][21][22][23]37,38,41 8 were validated for arm BP measurement 19,24-31 and 10 had not been validated 7,14,[20][21][22][23][32][33][34][35][36][37][38][39][40][41] ( Table 1). The heterogeneity (I 2 ) among the studies was 73%, and a Funnel plot indicates a minor publication bias (Figure 1).…”

“…Positive and negative study conclusion In 18 of the 25 studies reviewed in this paper (72%; n ¼ 3449), 7,14,[19][20][21][22][23][25][26][27][28]31,[34][35][36]38,40 the authors arrived at a conclusion in favor of oscillometric ABI measurement. Studies with Table 1a Studies that compared the oscillometric with Doppler method for ankle-brachial index measurement a positive conclusion compared with those with a negative one reported a lower but not significant average Doppler-oscillometric ABI difference (0.012±0.010 vs. 0.047±0.035 P ¼ 0.38) and absolute ABI difference (0.044 ± 0.011 vs. 0.060 ± 0.021; P ¼ 0.51), and a significantly higher sensitivity for PAD diagnosis (80 ± 3% vs. 51±5%; Po0.001).…”

“…(19). Many positive studies (15–18) reported only the correlation of ABI values between the Doppler and the automatic oscillometric method. However, as both methods measure the same parameter, a good correlation is predictable.…”
