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), cells decrease (Expand search), cost increase (Expand search)
decrease point » decreased point (Expand search), decreases joint (Expand search), decrease in (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease NOT decrease costs decrease ) OR ( decrease lesions decrease point pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease costs decrease ) OR ( decrease lesions decrease point pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease costs decrease ) OR ( decrease lesions decrease point pattern ))*.
