Perhaps you should try some spelling variations:
significantly smaller » significantly larger (Expand Search), significantly shorter (Expand Search), significantly higher (Expand Search)
significantly greater » significantly correlated (Expand Search), significantly increased (Expand Search), significantly decreased (Expand Search)
smaller decrease » small decrease (Expand Search), marked decrease (Expand Search), smaller areas (Expand Search)
greater decrease » greater increase (Expand Search), greater increases (Expand Search), rate 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 greater decrease )).
