Perhaps you should try some spelling variations:
decrease buried » decrease burden (Expand search), decrease during (Expand search), decrease observed (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their disease » the disease (Expand search), hair diseases (Expand search)
pain decrease » can decrease (Expand search), taping decrease (Expand search), strain decrease (Expand search)
disease pain » disease patient (Expand search), disease patients (Expand search), disease pd (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 their disease pain decrease ) OR ( decrease AND decrease buried objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease their disease pain decrease ) OR ( decrease AND decrease buried objects ))*.
