Receiver operating characteristic (ROC) curves to classify the false positivity in
METAVIR F1 to F3. Using alanine aminotransferase (ALT) levels (A) to discriminate the false positive in liver fibrosis evaluation using acoustic radiation
force impulse elastography (n = 32) from the non false positive (n = 77) of the 109
patients with METAVIR F1, F2 and F3, the area under ROC curve (AUC) was 0.715 (standard
error, SE, 0.053; 95% CI, 0.612-0.819; P < .001). The ALT level of 109.5 IU/L was the optimal cutoff value with a sensitivity
of 56.3% and a specificity of 81.8%. Using the ActiTest A scores (B), the optimal cutoff was 0.35 (AUC, 0.736; SE, 0.051; 95% CI, 0.636-0.835; P < .001; sensitivity, 93.8%; specificity, 41.6%).
