WebDec 8, 2015 · Here is the output of the coefficients (not hazard ratios just to be clear): v1 (binary) Coef: 1.347 (p < 0.001) v2 (discrete) Coef: 0.162 (p <0.001). This makes sense, since intuitively these are expected risk factors for readmission. If v1 = 1 then there's an increased likelihood of readmission.
