I'd like to know if I can use "proc phre" to find Hazard Ratio at a specific time point (i.e., 90 days), for example, use timelist=90 (but it does not work). Or I have to recode the data to set 90 days as the maximum time to get the hazard ratio at 90 days?
Unless a time-varying covariate is included in the model, hazard ratios associated with every term in the model are constant. If no time-varying covariate is in the model, simply calculate the hazard ratio of the variable you are interested in and you get what you want.

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
