In cohort studies, the risk ratio (RR) is one of the most commonly used epidemiologic indices to quantify the effect of a suspected risk factor on the probability of developing a disease. When we employ cluster sampling to collect data, an interval estimator that does not account for the intraclass correlation between subjects within clusters is likely… CONTINUE READING
