Perhaps you should try some spelling variations:
decrease burden » disease burden (Expand search), decrease further (Expand search)
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (Expand search)
burden affect » born affect (Expand search), boron affect (Expand search), burden after (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 cell decrease lipid decrease ) OR ( decrease to decrease burden affect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cell decrease lipid decrease ) OR ( decrease to decrease burden affect ))*.
