Notes: Duplicates were identified using the Endnote automated “find duplicates” function with preference set to match on title, author and year, and removed from your Endnote library. There will likely be additional duplicates found that Endnote was unable to detect.

Key to understanding OVID syntax:

/ = Subject Heading

Exp = explode

ADJ? = (adjacent to) within? number of words

mp. = title, abstract, keyword heading word, subject heading word

= truncation character
