Perhaps you should try some spelling variations:
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)
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 world » decrease work (Expand search), decrease food (Expand search), decrease or (Expand search)
world objects » sound objects (Expand search), world effects (Expand search), world aspects (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 decrease lipid decrease ) OR ( decrease AND decrease world objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease their decrease lipid decrease ) OR ( decrease AND decrease world objects ))*.
