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