Perhaps you should try some spelling variations:
rate decreases » rats decreases (Expand search), rate decrease (Expand search), water decreases (Expand search)
decreases food » decreases blood (Expand search), decreases and (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (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.

• Removing quotes may allow a broader search: (( decrease rate decreases food processing ) OR ( decrease _ decrease il decrease ))~.
