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 strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » stress decreases (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
risk object » disk object (Expand search), mask object (Expand search), task object (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 of decrease strain decrease ) OR ( decrease lesions decrease risk object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease strain decrease ) OR ( decrease lesions decrease risk object ))*.
