Perhaps you should try some spelling variations:
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)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
decrease about » disease about (Expand search), decrease akt (Expand search), decrease at (Expand search)
about objects » about subjects (Expand search), belt objects (Expand search), art objects (Expand search)

You may be able to get more results by adjusting your search query.

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