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