Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease in (Expand search)
owing decrease » taping decrease (Expand search), will decrease (Expand search), skins decrease (Expand search)
and processing » food processing (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease owing decrease to decrease ) OR ( decrease lesions decrease AND processing ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease owing decrease to decrease ) OR ( decrease lesions decrease and processing ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease owing decrease to decrease ) OR ( decrease lesions decrease and processing ))*.
