Prediction model of pregnancy outcome. A. The receiver operating characteristic (ROC) curves of a mixture of four features, including the mutated ZP gene, the protein domain where the mutation is located, the type of mutation, and the clinical phenotype of the patient. The area under the curve (AUC) is 0.898. B. The normalized confusion matrix shows the true positive rate is 1.00 and the true negative rate is 0.38. The study used one-hot coding, coding non-pregnancy as 1 and pregnancy as 0
