I need to know how to interpret the analysis of maximum likelihood estimates output in SAS after using a phrec procedure with backwards selection.
Attached is an example output.
The code looks something like this:
proc phreg data="map.sas7bdat";
model survival*censor(1) = After_Blood_Return __hr_After_60_Blood_Loss After_60_Blood_Loss _0_min_After_40_Blood_Loss After_40_Blood_Loss Before_Hypotension

Here's a good walk through of doing survival analysis with SAS
Your question is a bit too broad to answer otherwise, in my opinion.
