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 textual » decrease fetal (Expand search), decrease total (Expand search), disease textual (Expand search)
textual pattern » textual patterns (Expand search), textural patterns (Expand search), sexual pattern (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not 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 that decrease lesions decrease ) OR ( decrease NOT decrease textual pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease lesions decrease ) OR ( decrease NOT decrease textual pattern ))*.
