Perhaps you should try some spelling variations:
competing opinions » competing visions (Expand search), competing motivations (Expand search)
decrease processes » disease processes (Expand search), decay processes (Expand search), increase process (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decreases disease (Expand search)
opinions decrease » lesions decrease (Expand search), combinations decrease (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » and decrease (Expand search), can increase (Expand search), to decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease can decrease decrease processes ) OR ( competing opinions decrease decrease after ))~.
