当然，人们可以选测降低cut off value，但与此同时又会引入true discoveries 减少的问题。人们为了解决这种multiple testing problem，又推出了新的标准——q-value。q -value是p-value基于False Discovery Rate（FDR）的修正，如果说P-value可以告诉我们某一次试验出现假阳性的概率，q-value则可以告诉我们...
得到的HR的P就是写的是“nominal P value”，然而总体人群比较得到的P值就是正常的P值。
1、CO 值( Cut Off Value , CO):界值或阳性判定值,指某测量方法中用于区分阳性和阴性的数值。有两种判断方式:一种是大于CO 值判为阳性,否则为阴性,常见于ELISA实验中除竞争抑制法以外的方法,判断方法较为直观;另一种是小于CO 值判为阳性,否则为阴性,常见于ELISA 实验中的竞争抑制法,判断方法不直观,要求测量...

Proteins with altered expression following NRBP1 knockdown were defined with cut-off values of p-value ≤ 0.05, and a ≥ 2-fold change in either direction. Corresponding genes were interrogated using the Enrichr pathway analysis platform (https://maayanlab.cloud/Enrichr/). The Top 10 pathwa...

Additionally, simulations have shown it to be beneficial to introduce a cut-off value σ for the HIO feedback functions BO(r,R) and BP(r,R) as was proposed in [19]. That is, during each iteration we set(17)Bn(r,R)={Bn(r,R)if|Bn(r,R)|>σ,0if|Bn(r,R)|≤σ.Here, σ ...
P value was calculated by One-way ANOVA test with multiple comparisons adjustment. Tumor volume was calculated using Radiant software. “N” refers to number of mice per group. Center of the box plots shows median values, boxes extent from 25% to the 75% percentile, whiskers show minimum ...
