Perhaps you should try some spelling variations:
increased buffering » increased bleeding (Expand search), increased during (Expand search), increased bursting (Expand search)
buffering objects » suffering subjects (Expand search), buffer objects (Expand search), buffering effect (Expand search)
risk increased » risk increase (Expand search), is increased (Expand search), risk increasing (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (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 OR decrease NOT decrease ) OR ( decrease risk increased buffering objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease OR decrease NOT decrease ) OR ( decrease risk increased buffering objects ))*.
