Perhaps you should try some spelling variations:
"c largest decrease" » "c largest decreases" (Expand Search), "c marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "c large decrease" (Expand Search)
"n marked increased" » "n marked increase" (Expand Search), "n marked increases" (Expand Search), "n marked decrease" (Expand Search), "_ marked increased" (Expand Search), "a marked increased" (Expand Search), "_ market increased" (Expand Search)
"c larger decrease" » "c marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "c large decrease" (Expand Search), "_ large decrease" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"c largest decrease\") OR (((\"c larger decrease\") OR (\"n marked increased\"))))~".
• Removing quotes may allow a broader search: (( c largest decrease ) OR ((( c larger decrease ) OR ( n marked increased ))))~.
• Adding a wildcard symbol may retrieve word variants: (("c largest decrease") OR ((("c larger decrease") OR ("n marked increased"))))*.
