Perhaps you should try some spelling variations:
largest decrease » largest decreases (Expand Search), larger decrease (Expand Search)
cases increased » rate increased (Expand Search), levels increased (Expand Search)
marked decrease » marked increase (Expand Search)
ct largest » _ largest (Expand Search)
ct cases » c2 cases (Expand Search), chd cases (Expand Search), ckd cases (Expand Search)
n marked » _ marked (Expand Search), a marked (Expand Search), _ market (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 cases increased ) OR ((( ct largest decrease ) OR ( n marked decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( ct cases increased ) OR ((( ct largest decrease ) OR ( n marked decrease ))))*.
