Perhaps you should try some spelling variations:
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decreases treg » decrease treg (Expand search), decreases the (Expand search), decreases stress (Expand search)
decrease final » decrease fungal (Expand search), decrease fetal (Expand search), decrease renal (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
final object » penal object (Expand search), minimal object (Expand search), visual object (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 AND decreases treg decrease ) OR ( decrease during decrease final object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decreases treg decrease ) OR ( decrease during decrease final object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decreases treg decrease ) OR ( decrease during decrease final object ))*.
