Development of a heart failure filter for Medline: an objective approach using evidence-based clinical practice guidelines as an alternative to hand searching

Table 3 The final OvidSP Medline heart failure filter

#	Searches
1	heart failure.mp.
2	ventricular dysfunction, left.sh.
3	cardiomyopathy.mp.
4	left ventricular ejection fraction.mp.
5	Or/1-4

Note: The OvidSP Medline suffix '.mp.' forces a search on the title, abstract, subject headings, and chemical registry fields while the '.sh.' suffix forces a search on the subject headings field alone.
