Perhaps you should try some spelling variations:
significantly mitigated » significantly mediated (Expand Search), significantly elevated (Expand Search), significantly related (Expand Search)
significantly larger » significantly lower (Expand Search), significantly smaller (Expand Search), significantly higher (Expand Search)
mitigated decrease » estimated decrease (Expand Search)
larger decrease » marked decrease (Expand Search)

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

• Removing quotes may allow a broader search: (( significantly larger decrease ) OR ( significantly mitigated decrease )).
