Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease walking » increase walking (Expand search), decrease during (Expand search), decrease lodging (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
walking process » making process (Expand search), working process (Expand search), baking process (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain 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 walking process ) OR ( decrease in decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease walking process ) OR ( decrease in decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease walking process ) OR ( decrease in decrease lesions decrease ))*.
