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