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