You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"early postoperative applications\") OR (\"early postoperative application\"))~".
• Removing quotes may allow a broader search: (( early postoperative applications ) OR ( early postoperative application ))~.
• Adding a wildcard symbol may retrieve word variants: (("early postoperative applications") OR ("early postoperative application"))*.
