Can any one suggest a method to identify the interacting variable/s responsible for the higher HR in the adjusted model?</P> Wed, 07 Aug 2019 10:25:12 GMT Abimal_Zippi 2019-08-07T10:25:12Z https://communities.sas.com/t5/Statistical-Procedures/Multivariate-Cox-proportional-hazards-regression/m-p/579621#M28440 <P>Hello!</P><P>In the multivariate cox model, the Hazard ratio estimate for one of the explanatory variables rather increased in the adjusted model compared to the univariate Hazard ratio estimate.
