Perhaps you should try some spelling variations:
decrease methods » defense methods (Expand search), disease methods (Expand search), dense methods (Expand search)
methods affected » methods affect (Expand search), methods effect (Expand search), method affects (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to 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 faster decrease rate decrease ) OR ( decrease costs decrease methods affected ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease rate decrease ) OR ( decrease costs decrease methods affected ))*.
