survival analysis

I have the same code and data and every time I run that it gives me a different outcome (i.e. point estimate and confidence interval values). I run the code on a different system then it gave outcome that I had a few months ago and this is the one I was expecting to get. I know there is nothing wrong with scripts and the data file is also same then what could be the possible reasons behind that?

Hi, welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:
