1·The principle for selection of cutoff value is investigated.
探讨了指示阈值的选择原则。
2·The alpha-cutoff value is conventionally set at 0.05 (and used for the above analysis).
alpha 断开值按照惯例被设置为 0.05（上述分析使用的就是该值）。
3·The ROC curve provided a range of values for establishing a cutoff value for each significant variable.
ROC曲线哒建立提供了每个重要变量哒临界值哒值哒范围。
4·The optimal cutoff value of PCT for predicting a positive blood culture showed an increase as the estimated glomerular filtration rate declined.
在预测血培养阳性时，随着肾小球滤过率降低，PCT的最佳阈值升高。
5·Receiver operating characteristic curve (ROC) was used to evaluate the cutoff value of S-CEA level as a predicting factor for the prognosis of CRC.
应用ROC曲线探讨CEA作为结直肠术后复发的预测指标的意义及最佳临界值的划分。
6·This setting is used to find the location (or critical value) on the Chi Square sampling distribution that includes a tail area equal to the alpha-cutoff value (0.05).
该设置用于查找 X 平方分布的抽样分布中包含尾数区域等于 alpha 断开值（0.05）的位置（或临界值）。
7·As a predicting factor for the relapse and prognosis of CRC, the cutoff value of serum CEA level may be used as a diagnostic index different from the current diagnostic criteria for CRC.
作为影响预后的分层指标，血清cea的临界值可能与目前临床常用的诊断标准有所不同。
8·The Critical value is based upon the significance level (or alpha-cutoff level) set for the analysis.
临界值建立在为该分析设置的某一重要级别（即 alpha 断开级别）之上。
9·Using 60% of the baseline standardized uptake value as a cutoff point, the sensitivity of the approach was 61% after one course of chemotherapy, 89% after two and 88% after three.
利用基线标准摄入值的60%作为切断点，该方法的敏感性在化疗第一疗程后、第二疗程后、第三疗程后分别为61%、89%和88%。
10·The back clipping plane determines the cutoff point for rendering polygons. Here we're setting it to 5000. This value will vary depending on your coordinate system.
背景剪裁平面决定了展现多边形时剪裁的点数，在这里我们设定的值是5000，这个值取决于您使用的坐标系。
