Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
lesions care » lesions case (Expand search), lesions are (Expand search), lesions carta (Expand search)
risk objects » risk subjects (Expand search), disk object (Expand search), first objects (Expand search)
care risk » are risk (Expand search), caries risk (Expand search), fire risk (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 AND decrease can decrease ) OR ( decrease lesions care risk objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease can decrease ) OR ( decrease lesions care risk objects ))*.
