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