The importance of study power cannot be overstated in epidemiological research:
Validity of Results: Studies with low power are at risk of producing false-negative results, missing true associations or effects, which can lead to incorrect public health recommendations. Resource Allocation: Conducting adequately powered studies ensures that resources are used efficiently and ethically, avoiding wasteful research that cannot produce conclusive results. Reproducibility: High-powered studies are more likely to produce reproducible and reliable findings, which are essential for building a solid evidence base in public health.
