• Performing a fuzzy search may retrieve terms with similar spellings: (((("ct values decrease") OR ("auc values decrease"))) OR ("ct cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ct values decrease\") OR (\"auc values decrease\"))) OR (\"ct cases increased\"))".
• Removing quotes may allow a broader search: (((( ct values decrease ) OR ( auc values decrease ))) OR ( ct cases increased )).
• Adding a wildcard symbol may retrieve word variants: (((("ct values decrease") OR ("auc values decrease"))) OR ("ct cases increased"))*.
