Perhaps you should try some spelling variations:
significantly less » significantly lower (Expand Search), significantly reduce (Expand Search), significantly better (Expand Search)
lower decrease » larger decrease (Expand Search), linear decrease (Expand Search), we decrease (Expand Search)
teer decrease » mean decrease (Expand Search), greater decrease (Expand Search)
less decrease » mean decrease (Expand Search), we decrease (Expand Search), levels decreased (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 ((lower decrease) OR (teer decrease))\\") OR (\\"significantly less decrease\\"))\"".
• Removing quotes may allow a broader search: (( significantly ((lower decrease) OR (teer decrease)) ) OR ( significantly less decrease )).
