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)
"ct cases increased" » "ct levels increased" (Expand Search), "ct cycles increases" (Expand Search), "c2 cases increased" (Expand Search), "ktr cases increased" (Expand Search), "chd 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 (\"ct cases increased\"))~".
• Removing quotes may allow a broader search: (((( i values decrease ) OR ( i marked decrease ))) OR ( ct cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i values decrease") OR ("i marked decrease"))) OR ("ct cases increased"))*.
