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