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