Perhaps you should try some spelling variations:
decrease fear » decreased fear (Expand search), decrease fetal (Expand search), decreased heart (Expand search)
fear patterns » wear patterns (Expand search), tear pattern (Expand search), search patterns (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 il » decreased il (Expand search), decrease in (Expand search), decrease hiv (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: "(( decrease AND decrease the decrease ) OR ( decrease il decrease fear patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease the decrease ) OR ( decrease il decrease fear patterns ))*.
