QUESTION 5 If the risk of disease development in the exposed group is less than the risk of disease in the non-exposed group, we can say The RR < 1 and there may be a negative association between the exposure and the development of the disease (possibly protective). The RR > 1 and there may be a positive association between the exposure and the development of disease (possibly causal) The RR < 1 is less than one and there may be a positive association between the exposure and the development of the disease (possibly causal). O The RR > 1 and there may be a negative association between the exposure and the development of the disease (possibly protective).
