The example from the help file produces hazard ratios as default, and you have to request coefficients. I am having a hard time to believe that it behaves differently because of the imputation..

stcox load bearings

//    Replay results, but show coefficients rather than hazard ratios
stcox, nohr

Subject: st: multiple imputation and survival analysis

I'd like to run a cox regression in data declared survival after using
multiple imputation.

I ran the "ice" command then using the imputed data, the micombine command
followed by the stcox model.  However, this produced models with
coefficients rather than hazard rates.  Do you know how or if I can
interpret these, or how/can I get hazard rate coefficients? I tried adding
a ", hazard" after the command Stata told me the option was not allowed.

Any guidance would be greatly appreciated!
