Perhaps you should try some spelling variations:
decreased high » decreased in (Expand search), decreased risk (Expand search), decreased il (Expand search)
decrease loss » decrease costs (Expand search), decrease low (Expand search), decrease blood (Expand search)
loss decrease » loss decreases (Expand search), to decrease (Expand search), not decrease (Expand search)
not decreased » not decrease (Expand search), to decreased (Expand search), not increased (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
high objects » with objects (Expand search), big objects (Expand search), bright objects (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (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 loss decrease OR decrease ) OR ( decrease NOT decreased high objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease loss decrease or decrease ) OR ( decrease not decreased high objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease loss decrease or decrease ) OR ( decrease not decreased high objects ))*.
