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