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)
"auct values decrease" » "auct values increased" (Expand Search), "auc values decrease" (Expand Search), "ct values decrease" (Expand Search), "count values decrease" (Expand Search)
"ic cases increased" » "ic rate increased" (Expand Search), "ic levels increased" (Expand Search), "19 cases increased" (Expand Search), "_ cases increased" (Expand Search), "3 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: (((("auct values decrease") OR ("ic cases increased"))) OR ("i largest decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"auct values decrease\") OR (\"ic cases increased\"))) OR (\"i largest decrease\"))*".
• Removing quotes may allow a broader search: (((( auct values decrease ) OR ( ic cases increased ))) OR ( i largest decrease ))*.
