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