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