Perhaps you should try some spelling variations:
after accession » after admission (Expand search), after session (Expand search), after successive (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)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » stress decreases (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

You may be able to get more results by adjusting your search query.

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