What are the Key Elements of Epidemiological Evidence?
Several key elements are critical when evaluating epidemiological evidence:
1. Validity: The accuracy and truthfulness of the findings. 2. Reliability: The consistency of the findings over time. 3. Bias: Systematic errors that can affect the validity of the study. 4. Confounding: Factors that can distort the true relationship between the exposure and the outcome. 5. Causality: Establishing a cause-and-effect relationship between exposures and outcomes.
