Interpreting a contingency table involves calculating various epidemiological measures:
Prevalence: The proportion of individuals with a particular characteristic (e.g., disease) in a given population. Incidence: The number of new cases of a disease that occur in a specific population within a particular time period. Relative Risk (RR): The probability of an event occurring in the exposed group compared to the non-exposed group. It is calculated as (a/(a+b)) / (c/(c+d)). Odds Ratio (OR): The odds of an event occurring in the exposed group compared to the non-exposed group. It is calculated as (a/b) / (c/d).
