• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"100 mg decrease\") OR (((\"2 wt decrease\") OR (((\"_ we decrease\") OR (\"_ eb decrease\"))))))".
• Removing quotes may allow a broader search: (( 100 mg decrease ) OR ((( 2 wt decrease ) OR ((( _ we decrease ) OR ( _ eb decrease )))))).
• Adding a wildcard symbol may retrieve word variants: (("100 mg decrease") OR ((("2 wt decrease") OR ((("_ we decrease") OR ("_ eb decrease"))))))*.
