Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search)
marked decrease » marked increase (Expand Search)
large decrease » larger decrease (Expand Search), large increases (Expand Search), large degree (Expand Search)
ct largest » _ largest (Expand Search)
c marked » _ marked (Expand Search), a marked (Expand Search), n marked (Expand Search)
a large » _ large (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 largest decrease ) OR ((( a large decrease ) OR ( c marked decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( ct largest decrease ) OR ((( a large decrease ) OR ( c marked decrease ))))*.
