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