decreases weaning » increased weaning (Expand search), decreases spreading (Expand search), decreases pain (Expand search)
decrease ratio » decreased ratio (Expand search), decrease at (Expand search), decreased rate (Expand search)
ratio decrease » rate decrease (Expand search), rapid decrease (Expand search), ratio increase (Expand search)
weaning object » learning object (Expand search), learning objects (Expand search), teaching object (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease the (Expand search)
decrease of » decrease in (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 of decrease ratio decrease ) OR ( decrease AND decreases weaning object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decrease ratio decrease ) OR ( decrease and decreases weaning object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease ratio decrease ) OR ( decrease and decreases weaning object ))*.
