- *Search strategies are reported using Ovid's search engine syntax for MEDLINE. The PubMed syntax is embedded in PubMed's Clinical Queries (see Discussion). †Diff = Difference, comparing the development and validation data sets using the iterative method of Miettinen and Nurminen for two independent binomial proportions. None of the differences were statistically significant. sh = subject heading; exp = explode, a search term that automatically includes closely related indexing terms; : = truncation; tw = textword (word or phrase appears in title or abstract); mp = multiple posting (term appears in title, abstract, or MeSH heading).
