What Are the Challenges in Building an Evidence Base?
Several challenges can impede the development of a strong evidence base in epidemiology:
Data Limitations: Incomplete or inaccurate data can lead to biased results and incorrect conclusions. Confounding Factors: Uncontrolled confounding factors can distort the true relationship between exposure and outcome. Publication Bias: The tendency to publish positive findings over negative or null results can create a skewed evidence base. Resource Constraints: Limited resources can affect the scope and quality of epidemiological research.
