Perhaps you should try some spelling variations:
significantly linear » significant linear (Expand Search), significantly lower (Expand Search), significantly longer (Expand Search)
linear decrease » linear increase (Expand Search)
lower decrease » larger 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 ((lower decrease) OR (nn decrease))\\") OR (\\"significantly linear decrease\\"))\"".
• Removing quotes may allow a broader search: (( significantly ((lower decrease) OR (nn decrease)) ) OR ( significantly linear decrease )).
