Prospective Study
A Prospective Study (pronunciation: pruh-spek-tiv stuhd-ee) is a type of Epidemiological Study that involves the collection of data from a group of individuals who do not have the outcome of interest at the start of the study. The individuals are then followed over time to see if they develop the outcome of interest.
Etymology
The term "prospective" comes from the Latin word "prospectus" which means "look forward". In the context of a study, it refers to looking forward in time to see what happens to the study participants.
