Perhaps you should try some spelling variations:
decrease cooperative » decrease cooperation (Expand search), disease cooperative (Expand search), decreases postoperative (Expand search)
decreases weaning » increased weaning (Expand search), decreases spreading (Expand search), decreases pain (Expand search)
weaning decrease » taping decrease (Expand search), craving decrease (Expand search), training decreases (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (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: (( decreases weaning decrease in decrease ) OR ( decrease OR decrease cooperative process ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreases weaning decrease in decrease ) OR ( decrease or decrease cooperative process ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreases weaning decrease in decrease ) OR ( decrease or decrease cooperative process ))*.
