Perhaps you should try some spelling variations:
decrease patter » decrease after (Expand search), decrease litter (Expand search), decrease catheter (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
patter based » pattern based (Expand search), patterns based (Expand search), battery based (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)

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 _ decrease ) OR ( decrease rate decrease patter based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease il decrease _ decrease ) OR ( decrease rate decrease patter based ))*.
