The relative risk ratio is a critical measure in epidemiology that helps determine the likelihood of an outcome occurring in one group compared to another. A higher relative risk indicates a greater association between the exposure and the outcome, hence signaling a higher urgency for intervention.

A relative risk ratio of 2.45 suggests that individuals in one population are more than twice as likely to experience the outcome compared to another population. This significant increase in risk highlights a pressing need for targeted risk reduction strategies. It indicates that there may be factors within this population that are contributing to an elevated incidence of the adverse outcome, and addressing these could drastically improve health outcomes.

In contrast, a relative risk of 0.59 reflects a protective effect, suggesting a lower risk in that particular population compared to others, while a relative risk of 1.13 indicates a slight increase that may not necessarily warrant immediate intervention. A risk ratio of 1.79 does suggest an increased risk, but it is significantly lower than 2.45, which demonstrates that while it is an area of concern, it may not be as urgent as addressing the risk associated with a relative risk of 2.45.

Thus, focusing on the population with a relative risk of 2.45 allows community
