Diagnostic Accuracy of APRI for the Prediction of Significant Fibrosis in Various Studies.

APRI, aspartate aminotransferase-to-platelet ratio index; AUROC, area under the receiver operating characteristic; PPV, positive predictive value; NPV, negative predictive value; 95%CI, 95% confidence interval.APRI，天冬氨酸转氨酶-血小板比值指数（aspartate aminotransferase-to-platelet ratio index）；AUROC，受试者工作特征曲线下面积（area under the receiver operating characteristic）；PPV，阳性预测值（positive predictive value）；NPV，阴性预测值（negative predictive value）；95%CI，95%置信区间（95% confidence interval）
