Cox Proportional Hazards Model The PHREG procedure in SAS/STAT software performs regression analysis of survival or duration data based on the Cox proportional hazards model. Cox's semiparametric ...

The Cox model is a semiparametric model in which the hazard function of the survival time is given by where h 0 ( t ) is an unspecified baseline hazard function, x ( t ) is a vectors of covariate ...

Abbreviations: CCH, case-cohort design; CoxW, weighted Cox regression; LG, logistic regression; Opt, optimal design; SCCH, stratified case-cohort; SECC, stratified extreme case-control; TaoCox, Tao's ...

We used a Cox proportional-hazards regression model to examine simultaneously the effects of multiple covariates on survival. 20 In all models, the categorical variables were tested for trend and ...

We calculated the coefficient of determination (R 2) and the associated 95% CIs from the weighted linear regression model to measure the association between ORR, PFS, and OS by treatment effect.

The Cox regression model with spline functions was used to assess the relation between imputed anti-circumsporozoite antibodies as a time-varying covariate and protection against malaria.
