Classification to differentiate samples from postmenopausal breast cancer patients or postmenopausal healthy controls. a Probability of postmenopausal breast cancer in the training set. b ROC curves for the training set. The AUC was 87.25% (95% CI 79.82–94.68%). Classification of the test set consisted of 18 premenopausal breast cancer patients (red) and 25 premenopausal healthy controls (blue). c Classification of each sample. We used two cutoffs to assign the samples into three groups: 50% cases were classified into “Case” (probability of case > 50%), and 68% controls were classified into “Not case” (probability of case < 35%). Four cases and five controls stayed in “Uncertain.” d ROC for the test set. The AUC is 72% and the 95% CI is 56.01–88.44%
