PPV, Clinical specificity and Kappa of EIA and ChIA Assays in 3740 samples with parallel testing on each assay.

TP = true-positive, FN = false-negative, TN = true-negative, FP = false-positive, PPV = positive predictive value, CI = confidence interval.TP = 真阳性（true-positive），FN = 假阴性（false-negative），TN = 真阴性（true-negative），FP = 假阳性（false-positive），PPV = 阳性预测值（positive predictive value），CI = 置信区间（confidence interval）。
