WebJun 24, 2024 · Among the non-cured patients, suppose the new treatment reduces hazard from 1 to 0.5. Thus among the non-cured patients, the hazard ratio comparing the new treatment to control is 0.5, and this does not change over time, while in the cured patients, there is no effect of treatment (since they are cured).
WebThe relative risk (RR), also sometimes known as the risk ratio, compares the risk of exposed and unexposed subjects, while the odds ratio (OR) compares odds. A relative risk or odds ratio greater than one indicates an exposure to be harmful, while a value less than one indicates a protective effect. What does a relative risk of 1.3 mean? WebJun 3, 2016 · The hazard ratio is the ratio of these two expected hazards: h 0 (t)exp (b 1a)/ h 0 (t)exp (b 1b) = exp(b 1(a-b)) which does not depend on time, t. Thus the hazard is proportional over time. Sometimes the model is expressed differently, relating the relative hazard, which is the ratio of the hazard at time t to the baseline hazard, to the risk ...
