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 methods » defense methods (Expand search), disease methods (Expand search), dense methods (Expand search)
methods affected » methods affect (Expand search), methods affective (Expand search), methods effect (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells 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 OR decrease costs decrease ) OR ( decrease lesions decrease methods affected ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease OR decrease costs decrease ) OR ( decrease lesions decrease methods affected ))*.
