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)
i largest » _ largest (Expand Search)
i larger » _ larger (Expand Search), _ large (Expand Search), a large (Expand Search)
ct cases » c2 cases (Expand Search), chd cases (Expand Search), ckd cases (Expand Search)
i large » _ large (Expand Search), a large (Expand Search), via large (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: "(((( i largest decrease ) OR ( ((i larger) OR (i large)) decrease ))) OR ( ct cases increased ))~".
• Adding a wildcard symbol may retrieve word variants: (((( i largest decrease ) OR ( ((i larger) OR (i large)) decrease ))) OR ( ct cases increased ))*.
