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