Perhaps you should try some spelling variations:
significantly smaller » significantly higher (Expand Search), significantly lower (Expand Search), significantly greater (Expand Search)
smaller decrease » small decrease (Expand Search), marked decrease (Expand Search), smaller areas (Expand Search)
teer decrease » mean decrease (Expand Search), greater decrease (Expand Search)
_ decrease » _ decreased (Expand Search), _ decreasing (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 (_ decrease))\\") OR (\\"significantly smaller decrease\\"))\"".
• Removing quotes may allow a broader search: (( significantly ((teer decrease) OR (_ decrease)) ) OR ( significantly smaller decrease )).
