*The search strategy is reported using Ovid's search engine syntax for MEDLINE. The PubMed syntax is epidemiologic studies [MeSH]. †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. ‡exp = explode, a search term that automatically includes closely related indexing terms.
