Effective search strategies in epidemiology include:
1. Boolean Operators: Using AND, OR, and NOT to combine search terms and refine results. 2. MeSH Terms: Utilizing Medical Subject Headings (MeSH) in PubMed to enhance search precision. 3. Citation Tracking: Following citations within articles to find related studies. 4. PICO Framework: Structuring searches based on Population, Intervention, Comparison, and Outcome.
