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