Receiver operating curve. A ROC curve is a plot of the true positive rate against the false positive rate for the different possible cutoff points of the test battery. In this way the trade off between sensitivity and specificity is illustrated and an optimal cut-off value can be suggested. An ideal curve reflecting high sensitivity and high specificity would be positioned towards the left and the upper border with an area under the curve approaching 100%. The presented curve shows no tendency to perform this way.
