Perhaps you should try some spelling variations:
"i largest decrease" » "i largest decreases" (Expand Search), "i larger decrease" (Expand Search), "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"ct values decrease" » "ct values increased" (Expand Search), "_ values decrease" (Expand Search), "i values decrease" (Expand Search)
"3 cases increased" » "3 rate increased" (Expand Search), "3 levels increased" (Expand Search), "_ cases increased" (Expand Search), "19 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: "((((\"ct values decrease\") OR (\"3 cases increased\"))) OR (\"i largest decrease\"))~".
• Removing quotes may allow a broader search: (((( ct values decrease ) OR ( 3 cases increased ))) OR ( i largest decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ct values decrease") OR ("3 cases increased"))) OR ("i largest decrease"))*.
