Perhaps you should try some spelling variations:
nn decrease » _ decrease (Expand Search), mean decrease (Expand Search), gy decreased (Expand Search)
ng decrease » _ decrease (Expand Search), we decrease (Expand Search), gy decreased (Expand Search)
c decrease » c decreased (Expand Search), _ decrease (Expand Search), rc decreased (Expand Search)
a decrease » _ decrease (Expand Search), _ decreased (Expand Search), _ decreases (Expand Search)
50 nn » 50 ns (Expand Search), 50 ng (Expand Search), 50 n (Expand Search)
5 c » 25 c (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: "(( 5 c decrease ) OR ((( 50 nn decrease ) OR ( 5 ((ng decrease) OR (a decrease)) ))))~".
• Adding a wildcard symbol may retrieve word variants: (( 5 c decrease ) OR ((( 50 nn decrease ) OR ( 5 ((ng decrease) OR (a decrease)) ))))*.
