significantly less » significantly lower (Expand Search), significantly reduce (Expand Search), significantly better (Expand Search)
teer decrease » mean decrease (Expand Search), greater 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: "(( significantly teer decrease ) OR ( significantly less decrease ))~".
