Perhaps you should try some spelling variations:
marked decrease » marked increase (Expand Search)
values decrease » values increased (Expand Search), largest decrease (Expand Search)
rate increased » greater increase (Expand Search)
c marked » _ marked (Expand Search), a marked (Expand Search), n marked (Expand Search)
i values » _ values (Expand Search)
ct rate » hit rate (Expand Search), cue rate (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: "(((( c marked decrease ) OR ( ct rate increased ))) OR ( i values decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( c marked decrease ) OR ( ct rate increased ))) OR ( i values decrease ))*.
