  • “The AUC is a measure of the overall performance of a diagnostic test and can be interpreted as the average value of sensitivities for all possible specificities. The AUC has a value between 0 and 1 but is meaningful as a diagnostic test only when it is > 0.5. The larger the value, the better the overall performance of the test.”
