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 buried » decrease burden (Expand search), decrease observed (Expand search), decreases during (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
objects » object (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 during decrease to decrease ) OR ( decrease AND decrease buried objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during decrease to decrease ) OR ( decrease AND decrease buried objects ))*.
