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)
significantly i » significantly _ (Expand Search), significantly high (Expand Search), significantly less (Expand Search)
i decrease » _ decrease (Expand Search), a decrease (Expand Search), _ decreased (Expand Search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( significantly smaller decrease ) OR ( significantly i decrease ))~.
