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