Definition
Restriction is straightforward, convenient and inexpensive means to control confounding. It is a process of limiting the entrance into the study to individuals who fall within a specified category of a confounder. For example if sex is potential confounder, the study could include only men or only women. Similarly, control of age could be achieved by restricting admissibility to those within o narrow range that corresponds to a relatively homogeneous rate of disease incidence.
