Perhaps you should try some spelling variations:
"ct values increased" » "ct cases increased" (Expand Search), "ct also increased" (Expand Search), "ct rate increased" (Expand Search), "_ values increased" (Expand Search), "i values increased" (Expand Search)
"ct largest decrease" » "ct largest decreases" (Expand Search), "ct larger decrease" (Expand Search), "ct marked decrease" (Expand Search), "_ largest decrease" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i 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: "((\"ct values increased\") OR (((\"ct largest decrease\") OR (\"c large decrease\"))))~".
• Removing quotes may allow a broader search: (( ct values increased ) OR ((( ct largest decrease ) OR ( c large decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("ct values increased") OR ((("ct largest decrease") OR ("c large decrease"))))*.
