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 postal » decrease total (Expand search), decreased total (Expand search), decreases post (Expand search)
decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease in (Expand search)
owing decrease » taping decrease (Expand search), will decrease (Expand search), skins decrease (Expand search)
postal objects » metal objects (Expand search), social objects (Expand search), visual objects (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 owing decrease lesions decrease ) OR ( decrease AND decrease postal objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease owing decrease lesions decrease ) OR ( decrease AND decrease postal objects ))*.
