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 faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
toc effective » cost effective (Expand search), both effective (Expand search), anos effective (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
decrease to » decreased to (Expand search), decrease the (Expand search), decrease pro (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 faster decrease to decrease ) OR ( decrease lesions decrease toc effective ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease to decrease ) OR ( decrease lesions decrease toc effective ))*.
