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