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)
"b large decrease" » "b marked decrease" (Expand Search), "b large increases" (Expand Search), "b large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search)
"mri also increased" » "may also increased" (Expand Search), "men also increased" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("c larger decrease") OR ("b large decrease"))) OR ("mri also increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c larger decrease\") OR (\"b large decrease\"))) OR (\"mri also increased\"))*".
• Removing quotes may allow a broader search: (((( c larger decrease ) OR ( b large decrease ))) OR ( mri also increased ))*.
