摘　　要：本文从循证医学应用证据和创造证据两个方面介绍了避孕药具证据的检索方法与策略,指出应根据检索目的做出选择:若为应用证据,应根据证据级别的高低依次选择不同的数据库,用准确的检索词快速检索相关文献;若为创造证据,则应尽可能选择多个相关数据库,并采用不同的检索词全面检索相关文献。可根据检索目的及检出文献数量把握所选检索词的敏感度与特异度。In this paper, we introduce search strategies and methods of contraceptive evidence through two aspects of evidence-based medicine, namely, the application of evidence and the creation of evidence. We should make choices according to our objectives when we search clinical evidence. If we aim to apply evidence, we should sequentially choose different databases according to the quality of evidence and use accurate search terms to search relevant papers quickly; if we aim to create evidence, we should choose multiple related databases and use different search terms to retrieve relevant studies comprehensively. The sensitivity and specificity of the selected search terms can be identified according to our purposes and the number of the retrieved papers.
