Cumulative incidence graph meaning

WebCumulative probabilities for an interval are calculated by multiplying the interval survival rates up to that interval. For example, the chances of survival begin in interval one as 6/6, then are 5/6 in interval two, and 4/5 for interval three giving a cumulative survival rate (probability) in interval three of 6/6 × 5/6 × 4/5 = 0.667. WebThe denominator is the number of persons in the population at the start of the observation period. Cumulative Incidence = No. of new cases of disease or injury / Size of population at risk x 100. In contrast to prevalence, incidence is a measure of the occurrence of new cases of disease (or some other studied outcome) during a specified period ...
