ROC curve for detecting clinical progression of pulmonary MAC disease after diagnosis. a ROC curve of monocyte counts, b ROC curve of the MLR. ROC curve of the MLR shows that the sensitivity, specificity, and area under the curve are 76.9%, 58.5%, and 0.705, respectively, at a cutoff of 0.17 for identifying progression of pulmonary MAC disease after diagnosis. With a cutoff value of 0.21, the MLR predicts progression with a sensitivity of 44.2% and specificity of 75.6%.
