For TP, TN, FP, and FN value is number of case. For sensitivity, specificity, PPV, NPV, and PLR value is shown with 95% CI.
TP = true positive; TN = true negative; FP = false positive; FN = false negative; PPV = positive predictive value; NPV = negative predictive value; PLR = positive likelihood ratio.
