Prevalence and Incidence

Prevalence of CKD is the proportion of cases in the population at a given time. Incidence of CKD is the count or rate of new cases (or newly discovered cases) of CKD over time. Percentage of adults with CKD stages 1-4 from 1999-2016 has remained relatively unchanged. Incidence of treated ESRD increased by about 93% from 1990 to 2016 and the proportion of the overall incident population starting with a transplant remained at ~2% over the entire period.
