Perhaps you should try some spelling variations:
decreased rigid » decreased risk (Expand search), decreased high (Expand search), decreased ratio (Expand search)
decrease the » decreases the (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease can » decrease and (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (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 the decrease can decrease ) OR ( decrease in decreased rigid objects ))~.
