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 litter » increased litter (Expand search), decrease after (Expand search), decreases liver (Expand search)
litter decrease » faster decrease (Expand search), life decrease (Expand search)
decrease data » decrease at (Expand search), increase data (Expand search), decrease fetal (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 litter decrease data processing ) OR ( decrease _ decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease litter decrease data processing ) OR ( decrease _ decrease lesions decrease ))*.
