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)
"ct larger decrease" » "ct marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "c large decrease" (Expand Search)
"i rate increased" » "i greater increase" (Expand Search), "_ rate increased" (Expand Search), "i race increased" (Expand Search), "a rate increased" (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: "((\"i rate increased\") OR (((\"ct values decrease\") OR (\"ct larger decrease\"))))~".
• Removing quotes may allow a broader search: (( i rate increased ) OR ((( ct values decrease ) OR ( ct larger decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("i rate increased") OR ((("ct values decrease") OR ("ct larger decrease"))))*.
