Perhaps you should try some spelling variations:
decreased reality » increased reality (Expand search), decreased mortality (Expand search), decreased health (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
and decreased » and decreases (Expand search), and increased (Expand search)
reality based » reality and (Expand search), density based (Expand search), reliability based (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (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 during decrease toc decrease ) OR ( decrease AND decreased reality based ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease during decrease toc decrease ) OR ( decrease and decreased reality based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during decrease toc decrease ) OR ( decrease and decreased reality based ))*.
