How do I find references for a biomedical claim I have already written?
Enter a claim or research question, find candidate papers, then check their source records and available evidence. A related topic is not enough: the study must fit the specific statement you plan to cite.
- Enter one specific claim, preserving the population, intervention or exposure, and outcome.
- Review candidate titles, source records and available evidence; open the original paper for context.
- Compare the population, study design, outcome and evidence direction before citing or revising your wording.
- If no result matches, revise the query and search further. No match does not establish that evidence is absent.
