Perhaps you should try some spelling variations:
decrease buffer » decrease after (Expand search), decrease burden (Expand search), decrease suffering (Expand search)
buffer effects » buffer effect (Expand search), burger effects (Expand search), after effects (Expand search)
increase risk » increased risk (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt increase » gait increase (Expand search), ants increase (Expand search), and increase (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 akt increase risk decrease ) OR ( decrease in decrease buffer effects ))~.
