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