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 fear » decreased fear (Expand search), decrease fetal (Expand search), decreased heart (Expand search)
fear decrease » break decrease (Expand search), merr decreases (Expand search), can decrease (Expand search)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may decrease (Expand search)
in pattern » on pattern (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 any decrease lesions decrease ) OR ( decrease fear decrease in pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease any decrease lesions decrease ) OR ( decrease fear decrease in pattern ))*.
