Ratio comparing the probability of disease between two groups (exposed and non-exposed).
The relative risk (RR) compares the probability that a health event occurs in an exposed group versus a non-exposed group.
Relative risk is a fundamental epidemiological indicator for evaluating the impact of nutritional exposure on health. An RR of 1 means there is no difference between the groups, an RR > 1 indicates an increased risk, and an RR < 1 shows a reduced risk.
Evaluates the association between a nutritional exposure and disease in epidemiological studies.
Interpret the RR considering the confidence interval and the quality of the study. Use the RR in addition to other association measures for a complete evaluation. Be cautious with small sample sizes that can produce unstable estimates.
Relative risk quantifies how many times more (or less) likely a disease is among the exposed compared to the non-exposed.
