Perhaps you should try some spelling variations:
risk decreases » diet decreases (Expand search), life decreases (Expand search), oic decreases (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search), _ decrease (Expand search)
decrease en » decrease in (Expand search), decrease on (Expand search), decrease when (Expand search)
en object » an object (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: "(( decrease akt decrease risk decreases ) OR ( decrease the decrease en object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease risk decreases ) OR ( decrease the decrease en object ))*.
