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 doping » decrease during (Expand search), decrease owing (Expand search), decrease lodging (Expand search)
doping process » drying process (Expand search), dying process (Expand search), pulping process (Expand search)
decrease on » decrease of (Expand search), decrease or (Expand search), decrease and (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or decrease (Expand search)
in decrease » in decreased (Expand search), pain decrease (Expand search), and decrease (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 doping process ) OR ( decrease on decrease in decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease doping process ) OR ( decrease on decrease in decrease ))*.
