decreases spreading » disease spreading (Expand search), decreases weaning (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (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 faster decrease toc decrease ) OR ( decrease OR decreases spreading objective ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease faster decrease toc decrease ) OR ( decrease or decreases spreading objective ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease toc decrease ) OR ( decrease or decreases spreading objective ))*.
