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 marked decrease" » "ct marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "n marked decrease" (Expand Search)
"i care increased" » "i cases increased" (Expand Search), "i rate increased" (Expand Search), "i age increased" (Expand Search), "_ care increased" (Expand Search), "hiv care increased" (Expand Search), "iad care 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: "((\"i care increased\") OR (((\"i values decrease\") OR (\"ct marked decrease\"))))~".
• Removing quotes may allow a broader search: (( i care increased ) OR ((( i values decrease ) OR ( ct marked decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("i care increased") OR ((("i values decrease") OR ("ct marked decrease"))))*.
