Perhaps you should try some spelling variations:
"auc values decrease" » "auc values increased" (Expand Search), "auc largest decrease" (Expand Search)
"i larger decrease" » "i marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "i large decrease" (Expand Search), "_ large 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)

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 larger decrease\") OR (\"i dalys increased\"))))~".
• Removing quotes may allow a broader search: (( auc values decrease ) OR ((( i larger decrease ) OR ( i dalys increased ))))~.
• Adding a wildcard symbol may retrieve word variants: (("auc values decrease") OR ((("i larger decrease") OR ("i dalys increased"))))*.
