Perhaps you should try some spelling variations:
"ct largest decrease" » "ct largest decreases" (Expand Search), "ct larger decrease" (Expand Search), "ct marked decrease" (Expand Search), "_ largest decrease" (Expand Search)
"i values decrease" » "i values increased" (Expand Search), "_ values decrease" (Expand Search)
"i race increased" » "i rate increased" (Expand Search), "i age increased" (Expand Search), "i care increased" (Expand Search), "_ race increased" (Expand Search), "3 race 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 race increased\") OR (((\"i values decrease\") OR (\"ct largest decrease\"))))~".
• Removing quotes may allow a broader search: (( i race increased ) OR ((( i values decrease ) OR ( ct largest decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("i race increased") OR ((("i values decrease") OR ("ct largest decrease"))))*.
