"ct cases increased" » "ct rate increased" (Expand Search), "ct levels increased" (Expand Search), "c2 cases increased" (Expand Search), "chd cases increased" (Expand Search), "ckd cases increased" (Expand Search)
"ai large decrease" » "ai marked decrease" (Expand Search), "ai large increases" (Expand Search), "ai large degree" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search), "via large decrease" (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 (\"ai large decrease\"))) OR (\"ct cases increased\"))~".
• Removing quotes may allow a broader search: (((( i largest decrease ) OR ( ai large decrease ))) OR ( ct cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i largest decrease") OR ("ai large decrease"))) OR ("ct cases increased"))*.
