In the Commentary by Grossman and Messerli titled "Angiotensin II Receptor Blockers: Equal or Preferred Substitutes for ACE Inhibitors?" published in the July 10 issue of the ARCHIVES (2000;160:1905-1911), an error occurred in the text on page 1906, third column, the sixth and seventh lines. It should have read "response (as defined in the respective study) was more than 60%" rather than "response (as defined in the retrospective study) was more than 60%."
