Perhaps you should try some spelling variations:
"i largest decrease" » "i largest decreases" (Expand Search), "i larger decrease" (Expand Search), "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"auc values decrease" » "auc values increased" (Expand Search)
"5 mass increased" » "5 cases increased" (Expand Search), "5 causes increased" (Expand Search), "5 costs increased" (Expand Search), "15 mass increased" (Expand Search), "_ mass increased" (Expand Search), "a mass 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 (\"5 mass increased\"))) OR (\"i largest decrease\"))~".
• Removing quotes may allow a broader search: (((( auc values decrease ) OR ( 5 mass increased ))) OR ( i largest decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("auc values decrease") OR ("5 mass increased"))) OR ("i largest decrease"))*.
