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)
"_ dalys increased" » "_ values increased" (Expand Search), "_ also increased" (Expand Search), "_ cases increased" (Expand Search), "_ days increased" (Expand Search)
"ai large decrease" » "ai marked decrease" (Expand Search), "ai large increases" (Expand Search), "ai large degree" (Expand Search), "a large decrease" (Expand Search), "i 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 (\"ai large decrease\"))) OR (\"_ dalys increased\"))~".
• Removing quotes may allow a broader search: (((( i largest decrease ) OR ( ai large decrease ))) OR ( _ dalys increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i largest decrease") OR ("ai large decrease"))) OR ("_ dalys increased"))*.
