Perhaps you should try some spelling variations:
costs processing » cost processing (Expand search), post processing (Expand search), codas processing (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (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 that decrease costs processing ) OR ( decrease in decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease costs processing ) OR ( decrease in decrease lesions decrease ))*.
