Perhaps you should try some spelling variations:
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during disease » nursing disease (Expand search), urine disease (Expand search), ring disease (Expand search)
decrease peo » decrease pro (Expand search), decreases pest (Expand search), decrease cell (Expand search)

disease at » disease an (Expand search), disease and (Expand search), disease after (Expand search)
peo based » pso based (Expand search), zero based (Expand search), feco based (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 disease at decrease ) OR ( decrease OR decrease peo based ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease during disease at decrease ) OR ( decrease or decrease peo based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during disease at decrease ) OR ( decrease or decrease peo based ))*.
