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 burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
decrease first » disease first (Expand search), decrease risk (Expand search), decrease its (Expand search)
first object » first objects (Expand search), direct object (Expand search), first direct (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » not decrease (Expand search), to decrease (Expand search), _ 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 OR decrease lesions decrease ) OR ( decrease burden decrease first object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease lesions decrease ) OR ( decrease burden decrease first object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease lesions decrease ) OR ( decrease burden decrease first object ))*.
