阴性似然比

阳性似然比和阴性似然比分别在6.3-11.6和0.13-0.49之间。和另外两种方案进行了符合率的比较，结果位于两者之间。

Positive likelihood ratio and negative likelihood ratio were between 6.3-11.6 and 0.13-0.49 respectively .

阴性似然比依次为0.41、0.56、0.59和0.71。

The negative likelihood ratio priority were 0.41 、 0.56 、 0.59 and 0 . 71 , respectively .

数据收集和分析：计算阳性和阴性似然比（LR）和诊断比值比。

Data collection and analysis Positive and negative likelihood ratios ( LR ) and diagnostic odds ratios ( DOR ) were calculated .

各研究之间阳性和阴性似然比（LR）和诊断比值比有很大变异，由于可信区间宽，说明明显缺乏精确性。

There was wide variation in the positive and negative LR and DOR between the studies , with significant lack of precision demonstrated by wide confidence intervals .

其阳性似然比为75.43，阴性似然比为0.22。

The positive likelihood ratio and the negative were 75.43 and 0.22 respectively .

阴性似然比（LR~-）越小，则表明该试验阴性结果的临床价值愈高。

The less negative likelihood rate ( LR ~ - ), the higher valuation of negative results .
