Perhaps you should try some spelling variations:
decrease lesion » decrease adhesion (Expand search), decrease asian (Expand search), decrease soon (Expand search)
lesion patterns » lesion pattern (Expand search), design patterns (Expand search), lesions pattern (Expand search)
decreased will » decreased il (Expand search), decreased with (Expand search), decreased milk (Expand search)
and decreased » and decreases (Expand search), and increased (Expand search)
decrease and » decreases and (Expand search), decrease of (Expand search), decrease the (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 AND decreased will decrease ) OR ( decrease in decrease lesion patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decreased will decrease ) OR ( decrease in decrease lesion patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decreased will decrease ) OR ( decrease in decrease lesion patterns ))*.
