Test accuracy and number of genetic markers in the selected classification models in the 10-fold cross-validation procedure. In each of the eight ethnic population combinations, the testing accuracy and the number of genetic markers in the selected classification model in each of the 10-fold cross-validations are shown in the top and bottom panels, respectively. The top and bottom panels show box-whisker plots of the testing accuracy and the number of key predictive markers based on GE-only (green), 500 K-only (purple), Array6.0-only (red), 500 K + GE (orange), and Array6.0 + GE (yellow).
