Perhaps you should try some spelling variations:
"i values decrease" » "i values increased" (Expand Search), "i largest decrease" (Expand Search), "_ values decrease" (Expand Search)
"i marked decrease" » "i marked increase" (Expand Search), "_ marked decrease" (Expand Search), "_ market decrease" (Expand Search), "_ marker decrease" (Expand Search)
"ckd cases increased" » "ckd rate increased" (Expand Search), "ckd levels increased" (Expand Search), "chd cases increased" (Expand Search), "ad cases 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 (\"i marked decrease\"))) OR (\"ckd cases increased\"))~".
• Removing quotes may allow a broader search: (((( i values decrease ) OR ( i marked decrease ))) OR ( ckd cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i values decrease") OR ("i marked decrease"))) OR ("ckd cases increased"))*.
