Perhaps you should try some spelling variations:
decreased running » decreased during (Expand search), decreases weaning (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
pain decreased » pain decrease (Expand search), in decreased (Expand search), brain decreases (Expand search)
running object » using object (Expand search), mining object (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND decrease costs decrease ) OR ( decrease pain decreased running object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease costs decrease ) OR ( decrease pain decreased running object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease costs decrease ) OR ( decrease pain decreased running object ))*.
