WHY? According to the Cochrane Handbook Section 220.127.116.11 "Minimizing Bias":
Systematic reviews of interventions require a thorough, objective and reproducible search of a range of sources to identify as many relevant studies as possible (within resource limits). This is a major factor in distinguishing systematic reviews from traditional narrative reviews and helps to minimize bias and therefore assist in achieving reliable estimates of effects.
A search of MEDLINE alone is not considered adequate. A systematic review showed that only 30% - 80% of all known published randomized trials were identifiable using MEDLINE (depending on the area or specific question) (Dickersin 1994).
The same can be considered for any comprehensive search of the literature.
|PubMed vs OVID Medline|
PubMed = Public Medline
MEDLINE is the largest component of PubMed (http://pubmed.gov/), the freely accessible online database of biomedical journal citations and abstracts created by the U.S. National Library of Medicine (NLM®). In addition to MEDLINE citations, PubMed also contains, among other items, in-process citations which provide a record for an article before it is indexed with MeSH and added to MEDLINE or converted to out-of-scope status.

Health science research is often multidisciplinary. Below is a list of multidisciplinary databases to start you in the right path. You can also use these databases to conduct basic searches to 'scope' out a subject; quickly find seminal articles; and conduct bibliometrics research. We do not recommend searching these databases as part of a systematic review.
