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 anodic » decrease and (Expand search), decreased aerobic (Expand search), decrease candida (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
anodic effect » anode effect (Expand search), anabolic effect (Expand search), anomeric effect (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 _ decrease burden decrease ) OR ( decrease their decrease anodic effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease burden decrease ) OR ( decrease their decrease anodic effect ))*.
