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 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 OR decrease during depressed ) OR ( decrease the decrease fire patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease during depressed ) OR ( decrease the decrease fire patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease during depressed ) OR ( decrease the decrease fire patterns ))*.
