What it cumulative incidence rate?

Cumulative incidence is a measure of frequency, as in epidemiology where it is a measure of disease frequency during a period of time. Cumulative incidence is the incidence calculated using a period of time during which all of the individuals in the population are considered to be at risk for the outcome. It is sometimes referred to as the incidence proportion or the attack rate. Cumulative incidence is calculated by the number of new cases during a period divided by the number of people at risk in the population at the beginning of the study.

How do you calculate relative risk from incidence rate?

Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor). Then, divide the incidence rate of the exposed group by the incidence rate of the unexposed group (RR = Incidence Rate in Exposed / Incidence Rate in Unexposed). A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
