Perhaps you should try some spelling variations:
decrease relapse » decrease release (Expand search), increases relapse (Expand search), decrease renal (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (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 in decrease pro decrease ) OR ( decrease lipid decrease relapse after ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease pro decrease ) OR ( decrease lipid decrease relapse after ))*.
