Perhaps you should try some spelling variations:
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 risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease over » decreases over (Expand search), decrease liver (Expand search), decrease or (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
over effect » over effects (Expand search), cover effects (Expand search), order 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 lipid decrease toc decrease ) OR ( decrease risk decrease over effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lipid decrease toc decrease ) OR ( decrease risk decrease over effect ))*.
