Perhaps you should try some spelling variations:
decrease burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
decrease its » decreases its (Expand search), decrease with (Expand search), decrease in (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
its defect » its efect (Expand search), its perfect (Expand search), its effect (Expand search)

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

• Removing quotes may allow a broader search: (( decrease NOT decrease burden decrease ) OR ( decrease to decrease its defect ))~.
