Perhaps you should try some spelling variations:
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease fire » decreased fibre (Expand search), decrease liver (Expand search), decrease the (Expand search)
fire patterns » the patterns (Expand search), use patterns (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to 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 of decrease during depressed ) OR ( decrease in decrease fire patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease during depressed ) OR ( decrease in decrease fire patterns ))*.
