Cox DR: Regression models and life tables (with discussion). J R Stat Soc Ser B 1972; 34: 187–220. Cuzick J : The efficiency of the proportions test and the logrank test for censored survival data.

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 ...

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.

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 ...

Upregulated lncRNAs identified in the pAML training set were used to establish a regularized Cox regression model of event-free survival (EFS), yielding a 37 lncRNA signature (lncScore). Discretized ...

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 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 ...

Participants in UK Biobank, a prospective cohort, were asked to wear an accelerometer for 7 days, and we applied our machine-learning model to classify their movement behaviours. Using compositional ...
