Control group designs are primarily used to study the average effect of a variable on a large number of individuals by comparing outcomes between a group that is exposed to the variable (experimental group) and a group that is not (control group). This design is not specifically aimed at studying individual behavior or exclusively focused on lifesaving medication for critically ill patients, although it could be applied in such contexts.
