For variables in Survival analysis 3 - Using SPSS and R commander (survival plug-in) to carry out Cox regression (proportional hazard analysis)To see the others in this serie In the example discussed in the "Interpreting the Regression Coefficient" section of that manual, the predictor Age has a coefficient of 0.03. The hazard rate increases by 0.03 (3%) with each unit increase in Age. However, it does not follow that the duration is time is decreasing by the same percentage that the hazard is increasing. The coefficients in a Cox regression relate to hazard; a positive coefficient indicates a worse prognosis and a negative coefficient indicates a protective effect of the variable with which it is associated. The hazards ratio associated with a predictor variable is given by the exponent of its coefficient; this is given with a confidence interval under the "coefficient details" option in StatsDirect.
