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