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), "a largest decrease" (Expand Search), "via largest decrease" (Expand Search)
"d cases increased" » "d rate increased" (Expand Search), "d levels increased" (Expand Search), "ad cases increased" (Expand Search), "_ cases increased" (Expand Search), "3 cases increased" (Expand Search)
"i large decrease" » "i marked decrease" (Expand Search), "i large increases" (Expand Search), "i large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "via large decrease" (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 largest decrease\") OR (\"i large decrease\"))) OR (\"d cases increased\"))~".
• Removing quotes may allow a broader search: (((( i largest decrease ) OR ( i large decrease ))) OR ( d cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i largest decrease") OR ("i large decrease"))) OR ("d cases increased"))*.
