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 flow » decreases flow (Expand search), decrease low (Expand search), decrease food (Expand search)
flow decrease » flow increase (Expand search), to decrease (Expand search), not decrease (Expand search)
and patterned » and patterns (Expand search), and pattern (Expand search), in patterned (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (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 flow decrease the decrease ) OR ( decrease during decrease AND patterned ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease flow decrease the decrease ) OR ( decrease during decrease and patterned ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease flow decrease the decrease ) OR ( decrease during decrease and patterned ))*.
