FIGURE 1 A receiver operating characteristic curve. FPR = false positive ratio or 1 − specificity. TPR = true positive ratio or sensitivity. Results of a test that provides no useful information will plot along the dotted line connecting the anchor points. The plotted diamond-shaped points from a test that is very useful demarcate a large area under the curve above this line. Modified from Hunink et al. (4).
