Perhaps you should try some spelling variations:
decrease among » decreases along (Expand search), decreasing among (Expand search), disease among (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), and decrease (Expand search)
among objects » among subjects (Expand search), moving objects (Expand search), young objects (Expand search)
decreased to » decreased the (Expand search), decreased tgf (Expand search), decreased in (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 rate decrease OR decrease ) OR ( decreased to decrease among objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease OR decrease ) OR ( decreased to decrease among objects ))*.
