CI, confidence interval; CT, cardiothoracic; CVC, cross validation consistency; DM, diabetes mellitus; MDR-ER, balancing functions for adjusting the ratio in risk classes and classification errors for imbalanced cases and controls using multifactor-dimensionality reduction; OR, odds ratio; RR, risk ratio estimated from MDR-ER; TN, true negative; TP, true positive.
