Perhaps you should try some spelling variations:
decrease variable » decrease variability (Expand search), decreases available (Expand search), discrete variable (Expand search)
variable pattern » variable matter (Expand search), variate pattern (Expand search), variable water (Expand search)
decreased fear » decreased heart (Expand search), decreased mean (Expand search), decreased after (Expand search)
fear decrease » break decrease (Expand search), merr decreases (Expand search), can decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (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 in decrease AND decrease ) OR ( decreased fear decrease variable pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease AND decrease ) OR ( decreased fear decrease variable pattern ))*.
