The new OvidSP basic search interface is supposed to be designed to address this ambiguity.<BR/><BR/>Do MeSH get at this cause and effect? Sure, try asthma and obesity/adverse effects as MeSH attached to articles dealing with obesity's role in asthma.<BR/><BR/>The other point I wanted to make is that if you type in asthma first into a search engine and then obesity you'll see different results than if you type in obesity first.<BR/><BR/>Dean<b>Dean Giustini - <i>blogger</i></b>http://www.blogger.com/profile/02302595937988887519noreply@blogger.com
