WebMar 17, 2024 · In other words, the relative reduction in risk of death is always less than the hazard ratio implies. It is also a decreasing function of the time point at which it is assessed. For instance, in the example in Figure 1, a 40% hazard reduction implies risk reductions of 25% and only 14% in the 1-year and 2-year mortality rates, respectively. WebA fairer comparison–the hazard function. The hazard function fixes the three problems noted above. It adjusts for the fact that fewer people are alive at age 40 than at age 20.
