Perhaps you should try some spelling variations:
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
decrease pitch » decrease with (Expand search), decrease its (Expand search), decrease high (Expand search)

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

• Removing quotes may allow a broader search: (( decrease their decrease AND decrease ) OR ( decrease costs decrease pitch pattern ))~.
