Hi Mansoor,

Thanks for your question.
Coefficients associated to qualitative explanatory variables are linked to the difference in log(hazards ratio) between categories and a category of reference. To obtain the equivalent in hazards ratio, use the transformation exp(coefficient).

I hope this helps.
