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