Perhaps you should try some spelling variations:
decrease abuse » decreased base (Expand search), decreased use (Expand search), decrease age (Expand search)
abuse pattern » abuse patterns (Expand search), use pattern (Expand search), mature pattern (Expand search)
decrease akt » decrease and (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decrease low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)
decrease at » decrease and (Expand search), decrease in (Expand search), decrease of (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 akt decrease low decrease ) OR ( decrease at decrease abuse pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease low decrease ) OR ( decrease at decrease abuse pattern ))*.
