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