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)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
decrease local » decreases local (Expand search), decrease total (Expand search), decrease toc (Expand search)
local pattern » local patterns (Expand search), facial pattern (Expand search), axial pattern (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 lesions decrease to decrease ) OR ( decrease costs decrease local pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease to decrease ) OR ( decrease costs decrease local pattern ))*.
