Perhaps you should try some spelling variations:
decrease mortality » decreases mortality (Expand search), decreased mortality (Expand search), increase mortality (Expand search)
decrease statins » disease statins (Expand search)
statins decrease » statins increase (Expand search), taping decrease (Expand search), skins decrease (Expand search)
mortality caused » mortality and (Expand search), mortality due (Expand search), mortality after (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)

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

• Removing quotes may allow a broader search: (( decrease statins decrease in decreased ) OR ( decrease NOT decrease mortality caused ))~.
