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)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search)
"c2 rate increased" » "c2 greater increase" (Expand Search), "cue rate 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: (((("i largest decrease") OR ("c large decrease"))) OR ("c2 rate increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"i largest decrease\") OR (\"c large decrease\"))) OR (\"c2 rate increased\"))".
• Removing quotes may allow a broader search: (((( i largest decrease ) OR ( c large decrease ))) OR ( c2 rate increased )).
• Adding a wildcard symbol may retrieve word variants: (((("i largest decrease") OR ("c large decrease"))) OR ("c2 rate increased"))*.
