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)

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 that decrease AND decrease ) OR ( decrease during decrease placing objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease that decrease and decrease ) OR ( decrease during decrease placing objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease and decrease ) OR ( decrease during decrease placing objects ))*.
