Perhaps you should try some spelling variations:
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 path » decrease with (Expand search), decrease at (Expand search), decreases pain (Expand search)
path patterns » patch patterns (Expand search), death patterns (Expand search), catch patterns (Expand search)
decrease not » decrease of (Expand search), decrease at (Expand search), decrease on (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), any decrease (Expand search), salt decreases (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 NOT decrease akt decrease ) OR ( decrease during decrease path patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease akt decrease ) OR ( decrease during decrease path patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease akt decrease ) OR ( decrease during decrease path patterns ))*.
