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 split » decrease ipla2 (Expand search), decrease implicit (Expand search), decrease quality (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (Expand search)
urea decrease » the decrease (Expand search), or decrease (Expand search)
split pattern » point pattern (Expand search), gait pattern (Expand search)

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

• Removing quotes may allow a broader search: (( decrease lesions decrease urea decrease ) OR ( decrease AND decrease split pattern ))~.
