It is the difference between the log-hazard per one unit increment in E which is equivalent to the log of the hazard ratio. In the previous example a hazard ratio of 2 corresponds to a 67 chance of an early death. The hazard ratio then is.

The Mantel Haenszel approach.

The log of the hazard ratio is given by In general the hazard ratio can be computed by exponentiating the difference of the log-hazard between any two population profiles. Hazard ratio exp 1. Is it possible to calculate SD from 95CI. For interpretability we compute hazard ratios by exponentiating the parameter estimates.
