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 logging » decrease lodging (Expand search), decrease flooding (Expand search), decrease owing (Expand search)
logging pattern » loading pattern (Expand search), foraging pattern (Expand search), imaging pattern (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
pain decrease » can decrease (Expand search), strain decrease (Expand search), taping 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 NOT decrease lesions decrease ) OR ( decrease pain decrease logging pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease lesions decrease ) OR ( decrease pain decrease logging pattern ))*.
