multivariable cox regression analysis多变量Cox回归分析是一种用于研究多个因素对生存时间影响的统计方法,它是Cox比例风险模型的扩展。在多变量Cox回归分析中,研究者可以评估多个协变量(自变量)与生存时间(因变量)之间的关系,以及这些协变量之间的相互作用。 以下是进行多变量Cox回归分析的基本步骤: 1. 数据准备:收集...

“Due to the limited sample size, a univariate analysis was performed.”Perhaps the authors mean a univariable analysis (i.e., only unadjusted models were fitted). 此处即为univariate的错误用法。 总结 1、单一因变量的回归模型...

④Multivariable Cox regression analysis revealed that the expression of nm23 / C-erbB-2 and TNM were three important and independent prognostic factors for BC ; the hazard ratios of nm23,C-erbB-2 expression and TNM were 0.395,2.009, and 1.446 , respectively.[Conclusion]The expression of nm23/...
Multivariable Cox proportional hazards analysis In cohort studies, where the exposure precedes the outcome, data can be analyzed using multivariable Cox proportional hazards regression analysis, also known as survival analysis. In Cox proportional hazards models the effect of independent variables on surviva...
