"c marked decrease" » "c marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "n marked decrease" (Expand Search)
"822 cases increased" » "822 levels increased" (Expand Search), "822 cycles increases" (Expand Search), "8 cases increased" (Expand Search), "24 cases 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 largest decrease") OR ("c marked decrease"))) OR ("822 cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c largest decrease\") OR (\"c marked decrease\"))) OR (\"822 cases increased\"))*".
• Removing quotes may allow a broader search: (((( c largest decrease ) OR ( c marked decrease ))) OR ( 822 cases increased ))*.
