Vertaling van "positive predictive value" in Chinees

阳性预测率
阳性率
Positron emission tomography/computed tomography surveillance in patients with Hodgkin lymphoma in first remission has a low positive predictive value and high costs.
在首次缓解的霍奇金淋巴瘤患者中进行正电子发射体层摄影/计算机体层摄影监测的阳性预测值低并且花费高
The number of eye fixation(NEF) and the responsive search scores(RSS) were recorded and the sensitivity, the specificity and the positive predictive value were calculated.
记录凝视点数（NEF）和反应性探索分（RSS）； 计算敏感度、特异度、阳性预测值。
Factors of age, sensitivity, specificity, positive predictive value and cancer prevalence are critical for obtaining the desired balance between cancer detection and negative biopsy.
年龄因子，敏感性，特异性，阳性预测率和肿瘤流行性对在肿瘤筛查和阴性活检之间取得一个希望的平衡是很关键的
Abnormal nodes on CT scan warrant careful scrutiny, but the low positive predictive value of CT scan suggests that enlarged perihepatic nodes on CT alone do not necessarily equate to metastatic disease, and this finding by itself should not preclude consideration for hepatic resection.
CT扫描中的异常淋巴结需要仔细辨别，但是CT的阳性预测率低，提示只显示在CT扫描中的肝周肿大淋巴结不一定就等于是淋巴结转移，单只这一结果也不应考虑排除肝脏切除。
Lipoprotein variables in adolescence were classified according to NCEP and NHANES cut points and compared for their ability to predict abnormal levels in adulthood.With the use of diagnostic performance statistics(sensitivity, specificity, positive predictive value, negative predictive value, area under receiver operating characteristic curve)in pooled and cohort-stratified data, the NHANES cut points(compared with NCEP cut points)were more strongly predictive of low high-density lipoprotein cholesterol in adults but less predictive of high total cholesterol, high low-density lipoprotein cholesterol, and high triglyceride levels in adults.
在混合的、队列分层的资料中，通过使用诊断性效能统计学指标（敏感性、特异性、阳性预测值、阴性预测值、接受机操作特征曲线下面积），结果发现，与NCEP切点相比，NHANES切点能更好的预测成人低HDL-C水平，但较差的预测成人高总胆固醇、高LDL-C和高TG水平。
The sensitivity, specificity, negative predictive value, and positive predictive value of the Risk of Ovarian Malignancy Algorithm were estimated.
估计卵巢恶性肿瘤算法的风险的敏感性，特异性，阴性预测值和阳性预测值。
Positive predictive value: With respect to a clinical test for a disease, the extent to which testing positive indicates that one has or will develop the disease.
阳性预测值：临床检测的衡量度。即检测结果为阳性时，个体可能患病的程度。
The positive predictive value was defined as the proportion of patients with any evidence of response and who had a sustained virological response.
阳性的预测值定义为有任何应答证据的患者和已有持续病毒学应答的患者总的比率。
A level of more than three times the upper limit of normal has a positive predictive value of 95 percent for gallstone pancreatitis.
超过正常上限3倍对于胆石性胰腺炎的预测值为95％。
Decreasing the prostate specific antigen cut point to 2.0ng/ml and the prostate specific antigen velocity cut point to 0.40ng/ml per year in men 50 to 59 years old improved the cancer detection rate but decreased the positive predictive value.
在50-59岁组病人，前列腺特异性抗原和前列腺特异性抗原速度分别降低为2.0ng/ml和0.40ng/ml每年可以提高肿瘤的诊断率但降低了阳性率。
HPV DNA testing has been shown consistently to be superior to cytology in terms of sensitivity and positive predictive value and will become a major tool in cervical cancer screening, at least in the developed countries.
在宫颈癌的筛查中，HPV-DNA检测的灵敏性及阳性率明显优于传统细胞学检查，至少在发达国家它将成为宫颈癌筛查的主要工具。
Despite the strong association between CMV load and these outcomes, the clinical utility of a high CMV load is limited because of its low positive predictive value for these outcomes.
尽管 CMV 载量与这些结果联系紧密，但高 CMV 载量的临床效用有限，因为它对这些结果的阳性预测价值较低。
In one study consisting predominantly of Caucasian patients from Western Australia, HLA typing had a nearly 100% positive predictive value for the development of abacavir hypersensitivity (45).
其中由主要来自澳大利亚西部的高加索人组成的受试者的研究表明， HLA 型别几乎可以百分之百地成功预测该病人在使用阿巴卡韦后是否会出现超敏反应 （45 ） 。
