Perhaps you should try some spelling variations:
decreased lesions » decreased response (Expand search), decreased levels (Expand search), decreased neuron (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)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and 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 in decreased lesions decrease ) OR ( decrease at decrease costs basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased lesions decrease ) OR ( decrease at decrease costs basic ))*.
