Perhaps you should try some spelling variations:
means decrease » mean decrease (Expand Search), deaths decreased (Expand Search)
nn decrease » a decrease (Expand Search), mean decrease (Expand Search), gy decreased (Expand Search)
n decrease » a decrease (Expand Search), _ decreased (Expand Search), _ decreases (Expand Search)
_ decrease » _ decreased (Expand Search)
20 means » _ means (Expand Search), k means (Expand Search), a means (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: "(( 20 means decrease ) OR ( 50 ((((n decrease) OR (nn decrease))) OR (_ decrease)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( 20 means decrease ) OR ( 50 ((((n decrease) OR (nn decrease))) OR (_ decrease)) ))*.
