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)
"ct values decrease" » "ct values increased" (Expand Search), "_ values decrease" (Expand Search), "i values decrease" (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: "((((\"ct values decrease\") OR (\"i largest decrease\"))) OR (\"ct rate increased\"))~".
• Removing quotes may allow a broader search: (((( ct values decrease ) OR ( i largest decrease ))) OR ( ct rate increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ct values decrease") OR ("i largest decrease"))) OR ("ct rate increased"))*.
