decrease hearing » decreases healing (Expand search), decreases weaning (Expand search), decrease during (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)

not decrease » to decrease (Expand search), not increase (Expand search), and 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: (( decrease faster decrease hearing processing ) OR ( decrease risk increase NOT decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease faster decrease hearing processing ) OR ( decrease risk increase not decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease hearing processing ) OR ( decrease risk increase not decrease ))*.
