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