Perhaps you should try some spelling variations:
decreased base » decreased bone (Expand search), decreased brain (Expand search), decreased risk (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)
and decreased » and decreases (Expand search), and increased (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
base objects » based object (Expand search), use objects (Expand search), page objects (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 to decrease rate decrease ) OR ( decrease AND decreased base objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease rate decrease ) OR ( decrease and decreased base objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease rate decrease ) OR ( decrease and decreased base objects ))*.
