Perhaps you should try some spelling variations:
"a largest decrease" » "a largest decreases" (Expand Search), "a larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "a large decrease" (Expand Search), "a latest decrease" (Expand Search)
"i marked decrease" » "i marked increase" (Expand Search), "_ marked decrease" (Expand Search), "_ market decrease" (Expand Search), "_ marker 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: "((((\"a largest decrease\") OR (\"i marked decrease\"))) OR (\"ct rate increased\"))~".
• Removing quotes may allow a broader search: (((( a largest decrease ) OR ( i marked decrease ))) OR ( ct rate increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("a largest decrease") OR ("i marked decrease"))) OR ("ct rate increased"))*.
