Perhaps you should try some spelling variations:
significantly less » significantly lower (Expand Search), significantly reduce (Expand Search), significantly better (Expand Search)
significantly nn » significantly _ (Expand Search), significantly i (Expand Search), significantly onto (Expand Search)
less decrease » mean decrease (Expand Search), teer decrease (Expand Search), we decrease (Expand Search)
nn decrease » _ decrease (Expand Search), a decrease (Expand Search), mean 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 nn decrease ) OR ( significantly less decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( significantly nn decrease ) OR ( significantly less decrease ))*.
