• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"50 a decrease\") OR (((\"100 ng decrease\") OR (((\"5 wt decrease\") OR (\"5 ht decrease\"))))))*".
• Removing quotes may allow a broader search: (( 50 a decrease ) OR ((( 100 ng decrease ) OR ((( 5 wt decrease ) OR ( 5 ht decrease ))))))*.
