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