Symptoms had a similar sensitivity and specificity in HIV + and HIV − participants, but in HIV + participants they had a higher positive and a lower negative predictive value. HIV+的参与者和HIV-的参与者的症状具有类似的灵敏度和特异性,但是HIV+的参与者的阳性预测值较高,而阴性预测值(NPV)较低。
A similar strategy with focus on a high negative predictive value of successive investigations is proposed for the exclusion of HFNEF in patients with breathlessness and no signs of congestion. 上述检查相继进行具有较高的阴性预测值(NPV),因此,对那些气促但无充血体征的患者来说,可以用相似的策略来排除HFNEF。
The negative predictive value of dobutamine test was 100 %. 多巴酚丁胺负荷试验对术后心血管风险的阴性预测值(NPV)达100%。
The negative predictive value of HR-HPV was high, its detection rates increased with cervical lesion grades. HR-HPV阴性预测值(NPV)高,其检出率随宫颈病变级别的升高而增加。
The accuracy, sensitivity, specificity, positive predictive value, negative predictive value of four methods were calculated. 计算各方法的准确度、敏感度、特异度、阳性预测值、阴性预测值(NPV)。
