# Survival Analysis with Multiple Events

Suppose we have a population $P$ that we are interested in. We want to track the onset of particular conditions (i.e. $A$, $B$ and $C$). Suppose that as blood pressure drops, these events occur. So $C$ is associated with a higher level drop of blood pressure. How would we use survival analysis to analyze this situation?

You need to provide additional info. Are A, B, and C independent conditions? Can one condition be singled out as the condition of interest? Depending on this, you might consider other conditions as censoring or you might go to a competing risks approach...or event to a multi-state approach... – ocram Oct 9 '12 at 14:44
(+1) @ocram is right: your problem looks like competing risks or multistate: here is a gentle and very good introduction. – julien stirnemann Oct 10 '12 at 0:06
I'm in agreement that A, B and C need more detail - "competing risks" is actually a fairly wide range of potential solutions. – EpiGrad Oct 10 '12 at 2:22
