Abstract
Cohort design is the best design to determine event incidence. Its advantages include the possibility of evaluating whether there is a causal association between potential risk factors and a dichotomous outcome. The measure of effect in cohort studies is the Relative Risk. Among its disadvantages are the costs and difficulties involved in monitoring the cohorts, as well as the possibility of incurring in selection (as the cohorts are constructed) and information biases (how information is collected).
