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 risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease diel » decrease il (Expand search), decrease due (Expand search), decreases yield (Expand search)
diel pattern » diet patterns (Expand search), yield pattern (Expand search), axial pattern (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)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease risk decrease on decrease ) OR ( decrease lesions decrease diel pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease risk decrease on decrease ) OR ( decrease lesions decrease diel pattern ))*.
