"auc cases increased" » "auc rate increased" (Expand Search), "auc levels increased" (Expand Search), "all cases increased" (Expand Search), "ad cases increased" (Expand Search), "aaa cases increased" (Expand Search)
"i values decrease" » "i values increased" (Expand Search), "i largest decrease" (Expand Search), "_ values decrease" (Expand Search)

Try widening your search to All Fields.

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

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