From: Two logistic models for the prediction of hypothyroidism in pregnancy
The receiver operating characteristics (ROC) curves for models I and II in the initial study. The receiver operating characteristics (ROC) curve for model I is indicated by crosses (++++) while that for model II is indicated by broken lines (----). The ROC data used was generated by determining the sensitivities and specificities of each model at different cut-off points of the predicted probability scores of the patients with hypothyroidism.
