Perhaps you should try some spelling variations:
adhesion decreased » adhesin decreases (Expand search), deletion decreased (Expand search), lesions decreased (Expand search)
decrease adhesion » increases adhesion (Expand search), decrease asian (Expand search), decreases aggression (Expand search)
decreased risk » increased risk (Expand search), decreased in (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
risk object » disk object (Expand search), mask object (Expand search), task object (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease AND decrease can decrease ) OR ( decrease adhesion decreased risk object ))~.
