Perhaps you should try some spelling variations:
"c largest decrease" » "c larger decrease" (Expand Search), "c marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "a largest decrease" (Expand Search), "b largest decrease" (Expand Search)
"_ dalys increased" » "_ also increased" (Expand Search), "_ cases increased" (Expand Search), "_ days increased" (Expand Search)
"c large decrease" » "c larger decrease" (Expand Search), "c marked decrease" (Expand Search), "c large increases" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "b 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: "((((\"c largest decrease\") OR (\"c large decrease\"))) OR (\"_ dalys increased\"))~".
• Removing quotes may allow a broader search: (((( c largest decrease ) OR ( c large decrease ))) OR ( _ dalys increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("c largest decrease") OR ("c large decrease"))) OR ("_ dalys increased"))*.
