Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
pain decrease » can decrease (Expand search), taping decrease (Expand search), strain decrease (Expand search)
lesions case » lesion case (Expand search), lesions caused (Expand search), lesions based (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
decrease 50 » decrease 30 (Expand search), decrease in (Expand search), decrease _ (Expand search)
50 objects » _ objects (Expand search), 3d objects (Expand search), in objects (Expand search)
case pain » care pain (Expand search), scale pain (Expand search), cases main (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 lesions case pain decrease ) OR ( decrease of decrease 50 objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions case pain decrease ) OR ( decrease of decrease 50 objects ))*.
