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