Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions pattern » lesions after (Expand search), lesions better (Expand search)
decrease at » decrease and (Expand search), decrease in (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (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)
decrease to » decrease toc (Expand search), decreased to (Expand search), decrease the (Expand search)

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

• Removing quotes may allow a broader search: (( decrease at decrease on decrease ) OR ( decrease to decrease lesions pattern ))~.
