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)
"3 cases increased" » "3 rate increased" (Expand Search), "3 levels increased" (Expand Search), "_ cases increased" (Expand Search), "19 cases 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 larger decrease\") OR (\"c large decrease\"))) OR (\"3 cases increased\"))~".
• Removing quotes may allow a broader search: (((( c larger decrease ) OR ( c large decrease ))) OR ( 3 cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("c larger decrease") OR ("c large decrease"))) OR ("3 cases increased"))*.
