Estimating incidence from age-specific prevalence for irreversible diseases with differential mortality

Stat Med. 1986 Nov-Dec;5(6):573-8. doi: 10.1002/sim.4780050604.


We present a method for estimating incidence from age-specific prevalence data for an irreversible disease where the mortality risks may differ for persons with and without the disease. This method is an extension of previously presented methodology for estimating incidence from prevalence for a disease that does not entail differential mortality. An application to senile cataract illustrates the method.
