Perhaps you should try some spelling variations:
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease local » decreases local (Expand search), decrease total (Expand search), decrease toc (Expand search)
local patterns » global patterns (Expand search), clinical patterns (Expand search)
decrease treg » decrease the (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs 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 treg decrease AND decrease ) OR ( decrease their decrease local patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease treg decrease AND decrease ) OR ( decrease their decrease local patterns ))*.
