Clinical Therapies: Methodology

Supplementary Searching

Searches you undertake in databases relevant to your topic might not be sufficient to find all the available evidence to answer your research question. You may need to undertake supplementary searches to help you identify key articles, people, concepts or other avenues for exploration from your original search. The amount of supplementary searching will vary depending on the discipline of your topic but can include: 

  • Searching grey literature resources
  • Searching clinical trials registers
  • Citation searching
  • Contact study authors or experts in your topic
