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)
decreases sound » decreases and (Expand search), decreases food (Expand search), decreases soil (Expand search)
risk decreases » diet decreases (Expand search), life decreases (Expand search), oic decreases (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
sound objects » and objects (Expand search), sound effects (Expand search), boundary objects (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 to decrease lesions decrease ) OR ( decrease risk decreases sound objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease lesions decrease ) OR ( decrease risk decreases sound objects ))*.
