Model confusion matrix and receiver operating characteristic curve. Model accuracy = 78.4 %, sensitivity = 76 %, specificity = 80.8 %, positive predictive value = 79.2 %, negative predictive value = 77.8%, and the chi-square p-value = 0.000049. The prediction was performed using standard SVM with 2nd order polynomial.
