In epidemiology, searches can be categorized into several types:
1. Systematic Reviews: These involve a comprehensive and structured approach to searching for and synthesizing research evidence. 2. Literature Searches: These are less structured but aim to gather a broad range of studies on a particular topic. 3. Database Searches: Using specialized databases like PubMed, Scopus, and Embase to find relevant studies and articles. 4. Gray Literature Searches: Involves looking for non-peer-reviewed sources like reports, theses, and conference papers.
