Perhaps you should try some spelling variations:
"c largest decrease" » "c larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "c large decrease" (Expand Search)
"c marked decrease" » "c marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "n marked decrease" (Expand Search)
"i cases increased" » "i levels increased" (Expand Search), "i cycles increases" (Expand Search), "ic 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: (((("c largest decrease") OR ("c marked decrease"))) OR ("i cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c largest decrease\") OR (\"c marked decrease\"))) OR (\"i cases increased\"))*".
• Removing quotes may allow a broader search: (((( c largest decrease ) OR ( c marked decrease ))) OR ( i cases increased ))*.
