That is one other kind of observational research the place individuals with sure medical circumstances are in comparison with others with out the medical situation. Contributors are matched as intently as potential when it comes to age, gender, race, and different components.

Case-controlled research are often completed retrospectively (wanting again over time) and could also be used to find out danger components for growing sure ailments.
