Molcular Profile Cox Analysis 输入一个你想要的基因，比如RAC3，`Select Measure for plot可以设置OS，PFI，DSS和DFI`，然后点上方的搜索🔍，就可以看到出的图了 需要的结果 继续往下滚动鼠标，就可以看到数据了，而且还可以下载 数据在这 得到数据以后就可以用R画图了，注意，这里的HR和CI都是Log过的...

Multivariate Cox proportional hazards regression Finally, we combined the risk score with clinical characteristics to construct the prognostic model. The results were sequentially displayed by a forest plot using the R package “forestplot”. In addition, the nomogram provided information on the relationsh...
回归系数(The regression coefficients)。Cox模型结果中要注意的第二个特征是回归系数(coef)的符号。正值(+)意味着危险(死亡风险)较高,因此预后更差。1:男,2:女。Cox模型的R总结给出了第二组相对于第一组,即女性与男性的风险比(HR)。性别的β系数= -0.53表明在这些数据中,女性的死亡风险(低存活率)低于男性...
