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 treg » decrease the (Expand search), decrease their (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs decrease (Expand search)
decrease loss » decrease costs (Expand search), decrease low (Expand search), decrease blood (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 pro decrease treg decrease ) OR ( decrease loss decrease methods affected ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pro decrease treg decrease ) OR ( decrease loss decrease methods affected ))*.
