Perhaps you should try some spelling variations:
"c largest decrease" » "c larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "c large decrease" (Expand Search)
"c marked decrease" » "c marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "_ market decrease" (Expand Search)
"n marked decrease" » "n marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "_ market 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 marked decrease\") OR (\"n marked decrease\"))))~".
• Removing quotes may allow a broader search: (( c largest decrease ) OR ((( c marked decrease ) OR ( n marked decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("c largest decrease") OR ((("c marked decrease") OR ("n marked decrease"))))*.
