Figure 3

Receiver operating characteristic (ROC) curves for the support vector machine classification of LR+RT+ versus LR-RT+/LR-RT- groups within the estrogen receptor-positive (ER+) group (left part) and estrogen receptor-negative (ER-) group (right part). The specificity is defined as the fraction of the LR-RT+/LR-RT- patients correctly classified, and the sensitivity as the fraction of the LR+RT+ patients correctly classified. LR-RT- = no local recurrence, no radiotherapy given; LR-RT+ = no local recurrence after radiotherapy; LR+RT+ = local recurrence developed after radiotherapy.
