lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease with (Expand search)

or processing » poir processing (Expand search), or reprocessing (Expand search), air processing (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (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 OR processing ) OR ( decrease lesions decrease in decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease owing decrease or processing ) OR ( decrease lesions decrease in decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease owing decrease or processing ) OR ( decrease lesions decrease in decrease ))*.
