"auc values decrease" » "auc values increased" (Expand Search)
"ct cases increased" » "ct levels increased" (Expand Search), "ct cycles increases" (Expand Search), "c2 cases increased" (Expand Search), "ktr cases increased" (Expand Search), "chd cases increased" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("auc values decrease") OR ("c largest decrease"))) OR ("ct cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"auc values decrease\") OR (\"c largest decrease\"))) OR (\"ct cases increased\"))".
• Removing quotes may allow a broader search: (((( auc values decrease ) OR ( c largest decrease ))) OR ( ct cases increased )).
• Adding a wildcard symbol may retrieve word variants: (((("auc values decrease") OR ("c largest decrease"))) OR ("ct cases increased"))*.
