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 burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease in (Expand search)
owing patterns » wing patterns (Expand search), growing patterns (Expand search), showing patterns (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 _ decrease lesions decrease ) OR ( decrease burden decrease owing patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease lesions decrease ) OR ( decrease burden decrease owing patterns ))*.
