Hello, I have the following problem. I stratified my patient cohort into three ordered groups and performed multivariate adjusted Cox regression analysis on each group separately. Now I would like to calculate a p for trend across the hazard ratios that I got for the three groups. How can I do that if I only have the HR and the confidence interval? For example I got the following HRs for one endpoint:
1.09(0.68-1.74), 1.29(0.94-1.76) and 1.64(1.01-2.68). There is a trend but how do I calculate if it is significant?
