A public health researcher in Delhi is analyzing data from a cross-sectional survey of 5000 adults to assess the association between smoking and chronic obstructive pulmonary disease (COPD). The study found that among 1000 smokers, 200 had COPD, and among 4000 non-smokers, 100 had COPD. The researcher has calculated both the relative risk (RR = 4.0) and the odds ratio (OR = 2.67) for this association. However, the researcher is uncertain about which measure to report and how to interpret the findings in the context of public health policy recommendations. What is the most appropriate next step in analyzing and presenting these epidemiological findings?
