Perhaps you should try some spelling variations:
teer decrease » greater decrease (Expand Search)
mean decrease » a decrease (Expand Search)
nn decrease » _ decrease (Expand Search), a decrease (Expand Search), gy decreased (Expand Search)
we decrease » _ decrease (Expand Search), a decrease (Expand Search), use decreased (Expand Search)
5 mean » _ mean (Expand Search), a mean (Expand Search), i mean (Expand Search)
50 nn » 50 ns (Expand Search), 50 ng (Expand Search), 50 n (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: "(( 50 nn decrease ) OR ((( 5 ((we decrease) OR (teer decrease)) ) OR ( 5 mean decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( 50 nn decrease ) OR ((( 5 ((we decrease) OR (teer decrease)) ) OR ( 5 mean decrease ))))*.
