Perhaps you should try some spelling variations:
"auc values decrease" » "auc values increased" (Expand Search), "auc largest decrease" (Expand Search)
"i dalys increased" » "i values increased" (Expand Search), "i also increased" (Expand Search), "i cases increased" (Expand Search), "_ dalys increased" (Expand Search), "d dalys increased" (Expand Search), "_ daly's increased" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large 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 values decrease\") OR (\"i dalys increased\"))) OR (\"c large decrease\"))~".
• Removing quotes may allow a broader search: (((( auc values decrease ) OR ( i dalys increased ))) OR ( c large decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("auc values decrease") OR ("i dalys increased"))) OR ("c large decrease"))*.
