Perhaps you should try some spelling variations:
decrease lexical » decrease physical (Expand search), decreases local (Expand search), decrease fetal (Expand search)
lexical patterns » clinical patterns (Expand search), local patterns (Expand search), regional patterns (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease hiv (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease to decrease in decrease ) OR ( decrease risk decrease lexical patterns ))~.
