Perhaps you should try some spelling variations:
decrease block » decrease blood (Expand search), increase block (Expand search), decreases blood (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk increase » diet increase (Expand search)
block pattern » block patterns (Expand search), flock pattern (Expand search), block eastern (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
increase at » increase and (Expand search), increase in (Expand search), increase _ (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and 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 risk increase at decrease ) OR ( decrease akt decrease block pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease risk increase at decrease ) OR ( decrease akt decrease block pattern ))*.
