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