Hi All,
I had a quick question about how to determine the cut off p value in order to include relevant variables from univariate analysis into multivariate regression analysis. For example, in my analysis- I am looking at the different clinical parameters that are associated with increased risk of mortality. So I first performed the univariate regression analysis and then variable whose p-value was <0.30 on univariate analysis, were included in the final multivariate regression analysis to determine which ones really are associated with the mortality. Is this method correct? I remember seeing something like this in some papers but can’t find them now​:man_facepalming: If yes/no, would really appreciate if you guys could suggest something or guide me here? I don’t know how to answer reviewers questions on this
