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