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