Perhaps you should try some spelling variations:
cross decreased » causes decreased (Expand search), corn decreased (Expand search), loss decrease (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease cross » decrease costs (Expand search), increase cross (Expand search), decrease sucrose (Expand search)
decreased or » decrease or (Expand search), decreased rorc (Expand search), decreased mir (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
decrease of » decrease in (Expand search)
of object » of objects (Expand search), an object (Expand search), en object (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 cross decreased OR decrease ) OR ( decrease during decrease of object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease cross decreased or decrease ) OR ( decrease during decrease of object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cross decreased or decrease ) OR ( decrease during decrease of object ))*.
