Perhaps you should try some spelling variations:
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)
decrease total » decreased total (Expand search), increase total (Expand search), decrease fetal (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (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), or decrease (Expand search)
total vector » total factor (Expand search), total setor (Expand search), local vector (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 NOT decrease during decrease ) OR ( decrease toc decrease total vector ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease during decrease ) OR ( decrease toc decrease total vector ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease during decrease ) OR ( decrease toc decrease total vector ))*.
