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