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