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