Figure 2. — Association between calcaneal quantitative ultrasonographic (QUS) measures and dual-energy x-ray absorptiometric (DXA)–measured T scores. A, Receiver operating characteristic (ROC) curves for calcaneal QUS parameters from patients with DXA-evaluated hip T score below −1 or −1 or above, B, Prevalence of DXA-based hip T score below −1, according to BUA values. Area under the ROC values were 0.723 for the QUS index (QUI), 0.741 for estimated bone mineral density (eBMD), 0.769 for broadband ultrasound attenuation (BUA), and 0.720 for the speed of sound (SOS).
