Cox regression, non-significance

[Gilles-Protais]

Greetings dear members,
I have a dataset of 630 patients, with just 8 events, so when I run a Cox regression with Firth correction, I have that none of the variables taken under consideration,are significant. Please  are  there other ways to study or explore in such situations, 

thanks.

With 8 events in 630 patients, it's really not surprising that nothing is significant. I think it is also unlikely that another analysis method would return a different result. 

The real answer is that you don't have enough data to find statistical significance.
