This blog has been created to share PubMed search strategies. Search strategies posted here are not perfect. They are posted in the hope that others will benefit from the work already put into their creation and/or will offer suggestions for improvements. Librarians who wish to post comments on this blog or who wish to become authors are invited to e-mail me (Cindy Schmidt). I'm not posting my unmc.edu e-mail address here, but it's easy to find on the web : - ).
