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)
low objectivity » law objectivity (Expand search), of objectivity (Expand search), new objectivity (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)

decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease lesions decrease pain decrease ) OR ( decrease OR decrease low objectivity ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease pain decrease ) OR ( decrease or decrease low objectivity ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease pain decrease ) OR ( decrease or decrease low objectivity ))*.
