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