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