Diagnostic yield of Multiplex real-Time PCR in clinical specimens from patients with extrapulmonary tuberculosis and focal complications of brucellosis.

PPV = positive predictive value; NPV = negative predictive value; Positive LR = positive likelihood ratio, Negative LR = negative likelihood ratio.anot done for mathematical reasons (division by zero).阳性预测值（positive predictive value, PPV）、阴性预测值（negative predictive value, NPV）、阳性似然比（positive likelihood ratio）及阴性似然比（negative likelihood ratio）。因数学原因（除数为零）未完成相关计算。
