https://communities.sas.com/t5/Statistical-Procedures/Can-I-use-proc-phreg-to-find-Hazard-Ratio-at-a-specific-time/m-p/941611#M47019 <P>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?</P> Thu, 29 Aug 2024 03:00:29 GMT SeaMoon_168 2024-08-29T03:00:29Z https://communities.sas.com/t5/Statistical-Procedures/Can-I-use-proc-phreg-to-find-Hazard-Ratio-at-a-specific-time/m-p/941611#M47019 <P>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).

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.</P> Sun, 01 Sep 2024 04:06:47 GMT https://communities.sas.com/t5/Statistical-Procedures/Can-I-use-proc-phreg-to-find-Hazard-Ratio-at-a-specific-time/m-p/942111#M47027 Season 2024-09-01T04:06:47Z
