Perhaps you should try some spelling variations:
"c values increased" » "c cases increased" (Expand Search), "c dalys increased" (Expand Search), "c also increased" (Expand Search), "ct values increased" (Expand Search), "_ values increased" (Expand Search), "i values increased" (Expand Search)
"ct largest decrease" » "ct larger decrease" (Expand Search), "ct marked decrease" (Expand Search), "_ largest decrease" (Expand Search)
"auc values decrease" » "auct values decrease" (Expand Search), "au_ values decrease" (Expand Search), "aui 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: (((("auc values decrease") OR ("c values increased"))) OR ("ct largest decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"auc values decrease\") OR (\"c values increased\"))) OR (\"ct largest decrease\"))".
• Removing quotes may allow a broader search: (((( auc values decrease ) OR ( c values increased ))) OR ( ct largest decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("auc values decrease") OR ("c values increased"))) OR ("ct largest decrease"))*.
