The hazard ratio
Web21 Jun 2024 · Epidemiologists commonly use an adjusted hazard ratio or incidence density ratio, or a standardized mortality ratio, to measure a difference in all-cause mortality rates. They seldom translate it into an age-, time-, or probability-based measure that would be easier to communicate and to relate to. Web30 Jul 2024 · HR (Hazard Ratio) = exp(bi) The p-value for sex is 0.01 and HR (Hazard Ratio) is 0.57 indicating a strong relationship between the patients’ sex and decreased risk of death. For example, holding the other covariates constant, being female (sex=2) reduces the hazard by a factor of 0.58, or 42%. That means that females have higher survival chances.
