Perhaps you should try some spelling variations:
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 rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
costs basic » costs brasil (Expand search), costs brazil (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 AND decrease lesions decrease ) OR ( decrease rate decrease costs basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease lesions decrease ) OR ( decrease rate decrease costs basic ))*.
