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