Perhaps you should try some spelling variations:
means decrease » mean decrease (Expand Search), deaths decreased (Expand Search)
teer decrease » mean decrease (Expand Search), greater decrease (Expand Search)
nn decrease » _ decrease (Expand Search), mean decrease (Expand Search), gy decreased (Expand Search)
a decrease » _ decrease (Expand Search), _ decreased (Expand Search), _ decreases (Expand Search)
20 means » _ means (Expand Search), k means (Expand Search), i 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 ( 10 ((teer decrease) OR (((nn decrease) OR (a decrease)))) ))~".
• Adding a wildcard symbol may retrieve word variants: (( 20 means decrease ) OR ( 10 ((teer decrease) OR (((nn decrease) OR (a decrease)))) ))*.
