Perhaps you should try some spelling variations:
largest decrease » largest decreases (Expand Search), larger decrease (Expand Search), marked decrease (Expand Search)
cases increased » rate increased (Expand Search), levels increased (Expand Search)
ct largest » _ largest (Expand Search)
ct values » _ values (Expand Search)
i values » _ values (Expand Search)
i cases » _ cases (Expand Search), 3 cases (Expand Search), 8 cases (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: "(((( ((ct values) OR (i values)) decrease ) OR ( ct largest decrease ))) OR ( i cases increased ))~".
• Adding a wildcard symbol may retrieve word variants: (((( ((ct values) OR (i values)) decrease ) OR ( ct largest decrease ))) OR ( i cases increased ))*.
