Perhaps you should try some spelling variations:
decrease abuse » decreased base (Expand search), decreased use (Expand search), decrease age (Expand search)
abuse patterns » abuse pattern (Expand search), use patterns (Expand search), age patterns (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), increase rate (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il decrease » l decrease (Expand search), will decrease (Expand search), oil decreases (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » that decrease (Expand search), and decrease (Expand search), not 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 il decrease at decrease ) OR ( decrease rate decrease abuse patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease il decrease at decrease ) OR ( decrease rate decrease abuse patterns ))*.
