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 low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)
decrease old » decrease food (Expand search), decrease of (Expand search), decrease and (Expand search)
old objects » world objects (Expand search), older objects (Expand search), road objects (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 _ decrease lesions decrease ) OR ( decrease low decrease old objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease lesions decrease ) OR ( decrease low decrease old objects ))*.
