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 that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease big » decrease high (Expand search), decrease in (Expand search), decrease hiv (Expand search)
big objects » bim objects (Expand search), using objects (Expand search), belt objects (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease that decrease AND decrease ) OR ( decrease lesions decrease big objects ))~.
