decrease further » increase further (Expand search), disease further (Expand search), decrease the (Expand search)
further decrease » further increase (Expand search), faster decrease (Expand search), the decrease (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break 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 further decrease _ decrease ) OR ( decrease risk decrease disc patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease further decrease _ decrease ) OR ( decrease risk decrease disc patterns ))*.
