It means that Suppose that a random event occurs, on the average, once every 100 years. The risk (or probability) that this event will occur in any 10-year period is:
Risk = 1 - [1 - 1/(R.I.)]n
= 1- [1 - 1/(100)]10
= 1 - [0.99]10 = 0.096 (or 9.6%)
Similarly, we can calculate the cumulative risks for various other time periods (for R.I. = 100):
TIME PERIOD (n) [1 - 1 / (R.I.)]n CUMULATIVE RISK 20 years 0.82 18% 25 years 0.78 22% 69 years 0.50 50% 100 years 0.37 63%

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.
