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 during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
during papers » during pars (Expand search), working papers (Expand search), during part (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 lesions decrease OR decrease ) OR ( decrease risk decrease during papers ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease OR decrease ) OR ( decrease risk decrease during papers ))*.
