Perhaps you should try some spelling variations:
"b larger decrease" » "b marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "b large decrease" (Expand Search), "_ large decrease" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search)
"c rate increased" » "c greater increase" (Expand Search), "_ rate increased" (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: (((("c large decrease") OR ("b larger decrease"))) OR ("c rate increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c large decrease\") OR (\"b larger decrease\"))) OR (\"c rate increased\"))*".
• Removing quotes may allow a broader search: (((( c large decrease ) OR ( b larger decrease ))) OR ( c rate increased ))*.
