The Significance of Ultrasound in Determining Whether SHPT Patients Are Sensitive to Calcitriol Treatment

Figure 2

The ROC analysis of morphology, size, number, and blood flow. The ROC analysis of morphology showed that the area under the curve was 0.88 and the cut-off value was 1.5 with sensitivity of 66.7% and specificity of 94.4%. The ROC analysis of size showed that the area under the curve was 0.91 and the cut-off value was 438.50 mm³ with sensitivity of 87.5% and specificity of 77.8%. The ROC analysis of number of PTGs showed that the area under the curve was 0.89 and the cut-off value was 2.5 with sensitivity of 66.7% and specificity of 100%. The ROC analysis of blood flow showed that the area under the curve was 0.86 and the cut-off value was 1.5 with sensitivity of 83.3% and specificity of 72.2%.
