Perhaps you should try some spelling variations:
"c larger decrease" » "c marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "c large decrease" (Expand Search), "_ large decrease" (Expand Search)
"b large decrease" » "b marked decrease" (Expand Search), "b large increases" (Expand Search), "b large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search)
"c greer increase" » "c greater increase" (Expand Search), "c greater increases" (Expand Search), "c year increase" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("b large decrease") OR ("c larger decrease"))) OR ("c greer increase"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"b large decrease\") OR (\"c larger decrease\"))) OR (\"c greer increase\"))*".
• Removing quotes may allow a broader search: (((( b large decrease ) OR ( c larger decrease ))) OR ( c greer increase ))*.
