Aggregate results are crucial for several reasons:
1. Public Health Interventions: They help in designing and implementing effective public health interventions by identifying high-risk groups and determining the impact of various factors on health. 2. Policy Making: Policymakers use these results to formulate evidence-based health policies. 3. Health Care Planning: They assist in resource allocation and planning of health care services. 4. Understanding Disease Dynamics: By examining these results, researchers can better understand the epidemiological triad of agent, host, and environment.
