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