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)
decreasing costs » decreasing cost (Expand search), decreasing rest (Expand search), decrease costs (Expand search)
at decreasing » and decreasing (Expand search), fit decreasing (Expand search), by decreasing (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (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 at decreasing costs basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease lesions decrease ) OR ( decrease at decreasing costs basic ))*.
