Perhaps you should try some spelling variations:
significantly increased » significant increase (Expand Search)
significantly slight » significantly lighter (Expand Search), significantly high (Expand Search), significantly higher (Expand Search)
increased decrease » increased release (Expand Search), increased crash (Expand Search)
slight decrease » slight increase (Expand Search)

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

• Removing quotes may allow a broader search: (( significantly increased decrease ) OR ( significantly slight decrease ))*.
