If you build a time-varying covariate for a chronic disease, e.g. diabetes, chronic kidney disease, etc, you can calculate how many people have diabetes at baseline, e.g. when they enter the cohort, and at the end of follow-up. So you can know how many people enter the cohort disease-free but develop the disease during follow-up.
