242 chapter 2 Figure 77. Bayesian probability plot of qualitative elastosonography Bayesian conditional probability plot showing the post-test probabilities versus prior probabilities of qualitative elastosonography to predict malignancy in indeterminate thyroid nodules, using the estimated summary likelihood ratios. Positive LR = 4.27 (95% CI: 1.37-13.3). Negative LR = 0.25 (95% CI: 0.14-0.45). Figure 76. SROC curve of qualitative elastosonography Summary receiver operating characteristic plot showing sensitivity versus 1-specificity of qualitative elastosonography in indeterminate thyroid nodules with available histopathology. AUC = 0.85 (95% CI: 0.82-0.88). AUC, area under the curve; HSROC, hierarchical summary receiver operating characteristic.
