Perhaps you should try some spelling variations:
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease common » increase common (Expand search), decrease soon (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
common basic » common base (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 can decrease during depressed ) OR ( decrease NOT decrease common basic ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease can decrease during depressed ) OR ( decrease not decrease common basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease can decrease during depressed ) OR ( decrease not decrease common basic ))*.
