Abstract

A follow-up study on chronic diseases usually needs to be large with a long follow-up period to provide a sufficient number of cases to be informative. Most of the participants in the study will provide little information since they will remain disease-free. A case–-control sampling strategy may sometimes be possible and it can usually be conducted at a much lower cost than a follow-up.
