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