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 variate » decreases ovarian (Expand search), decrease intimate (Expand search), decrease striatal (Expand search)
variate pattern » variable pattern (Expand search), variant pattern (Expand search), marriage pattern (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 NOT decrease variate pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease lesions decrease ) OR ( decrease NOT decrease variate pattern ))*.
