Hazard ratio of 1.2
WebThe 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. The hazards ratio may also be thought of as the relative death rate, see Armitage and Berry (1994).
