Perhaps you should try some spelling variations:
significantly alter » significantly altered (Expand Search), significantly smaller (Expand Search), significantly better (Expand Search)
significantly mean » significantly less (Expand Search), significantly mediate (Expand Search), significantly impact (Expand Search)
alter decrease » larger decrease (Expand Search), water decreases (Expand Search), teer decrease (Expand Search)
mean decrease » a decrease (Expand Search)

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

• Removing quotes may allow a broader search: (( significantly mean decrease ) OR ( significantly alter decrease )).
