Literature Search Strategy
In order to review the most relevant scientific literature available, the committee and staff regularly conducted thorough searches of several online bibliographic data bases, including Medline, Science Direct, and WorldCat/First Search. General searches on vitamin D, calcium, and health outcomes were first conducted to identify primary literature. Using the results of the primary search, key search terms were developed and secondary searches were then conducted. Search terms were also chosen based on relevance to the report outline and topics included in the previous IOM report (IOM, 1997). Although initial searches were general, subsequent searches focused on retrieving studies that were not covered by the evidence-based reviews conducted by AHRQ-Ottawa (Cranney et al., 2007) and AHRQ-Tufts (Chung et al., 2009). Similar to the methodology used by the AHRQ reports searches were limited to English. As the study progressed, focused searches were conducted as needed and general searches were carried out to identify newly published articles. See Box E-1 for an example of how searches were conducted.
