A rate ratio compares the incidence rates, person-time rates, or mortality rates of two groups. As with the risk ratio, the two groups are typically differentiated by demographic factors or by exposure to a suspected causative agent. An incident rate provides information about recordable injuries and illnesses. The U.S. Department of Labor's Occupational Safety and Health Administration and individual employers use the information to plan for upcoming inspections, gauge the effectiveness of health and safety programs within a single firm, and make industry-wide comparisons. Rate ratio for mortality between men and women = 7.7/17.4 = 0.44 [95% CI 0.08 to 2.37] where the rates have been calculated as deaths per 100 person-years by dividing the number of deaths within each sex by the total number of years of follow-up in each sex Calculate incidence rate of disease based on total number of new cases of specific disease and total population at risk using this online calculator.

An incidence rate ratio is the ratio of two rates - for example e1/N1 / e2/N2 where e1 & e2 are the number of events in each population and N1 & N2 are the size of the two groups, midway through the time period. In epidemiological parlance it is the ratio of the incidence rates in exposed and unexposed individuals. The term 'incidence rate ratio" assumes that you're fitting a model with an exposure() (offset) term as well, typically specifying the time each unit was observed for, in which case instead of expected counts you have expected counts per unit time, i.e. rates. Calling them incidence rates is terminology from epidemiology. With the multiplicative Poisson model, the exponents of coefficients are equal to the incidence rate ratio (relative risk). These baseline relative risks give values relative to named covariates for the whole population.

Rate ratio for mortality between men and women = 7.7/17.4 = 0.44 [95% CI 0.08 to 2.37] where the rates have been calculated as deaths per 100 person-years by dividing the number of deaths within each sex by the total number of years of follow-up in each sex

Thus, the incidence rate is the ratio of the number of cases to the total time the population is at risk of disease. Method for calculating incidence rate Number of new cases of disease or injury during specified period Time each person was observed, totaled for all persons
