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