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 burgers » decrease burden (Expand search), decrease further (Expand search)
burgers effect » burgers effects (Expand search), surgery effect (Expand search), burger effects (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (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 OR decrease on decrease ) OR ( decrease lesions decrease burgers effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease OR decrease on decrease ) OR ( decrease lesions decrease burgers effect ))*.
