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), "auc values increased" (Expand Search)
"au_ values decrease" » "au_ largest decrease" (Expand Search), "auc values decrease" (Expand Search), "_ values decrease" (Expand Search), "all values decrease" (Expand Search)
"i values decrease" » "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 values increased") OR ("au_ values decrease"))) OR ("i values decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c values increased\") OR (\"au_ values decrease\"))) OR (\"i values decrease\"))".
• Removing quotes may allow a broader search: (((( c values increased ) OR ( au_ values decrease ))) OR ( i values decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("c values increased") OR ("au_ values decrease"))) OR ("i values decrease"))*.
