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