Perhaps you should try some spelling variations:
significantly greater » significantly correlated (Expand Search), significantly increased (Expand Search), significantly higher (Expand Search)
greater decrease » greatest decrease (Expand Search), greater increase (Expand Search), greater disease (Expand Search)
a decrease » _ decreased (Expand Search), _ decreases (Expand Search), mean decrease (Expand Search)
_ decrease » _ decreased (Expand Search), _ decreasing (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"significantly greater decrease\\") OR (\\"significantly ((a decrease) OR (_ decrease))\\"))\"".
• Removing quotes may allow a broader search: (( significantly greater decrease ) OR ( significantly ((a decrease) OR (_ decrease)) )).
