Perhaps you should try some spelling variations:
risk decreases » diet decreases (Expand search), life decreases (Expand search), oic decreases (Expand search)
decreases belt » decreases cell (Expand search), decreases pest (Expand search), decreases breast (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
objects » object (Expand search)

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

• Removing quotes may allow a broader search: (( decrease OR decrease to decrease ) OR ( decrease risk decreases belt objects ))~.
