Perhaps you should try some spelling variations:
decrease opposing » decrease following (Expand search), decrease owing (Expand search), decrease flooding (Expand search)
opposing effects » opposite effects (Expand search), coupling effects (Expand search), doping effects (Expand search)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » stress decreases (Expand search)
decrease break » decreases breast (Expand search), decreases areas (Expand search), decrease treg (Expand search)
break decrease » urea 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 NOT decrease strain decrease ) OR ( decrease break decrease opposing effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease strain decrease ) OR ( decrease break decrease opposing effects ))*.
