摘要

Drs Thombs and Ziegelstein note 3 differences between our study registration in May 2010 and the protocol published in BioMed Central (BMC) Health Services Research1 in April 2013 and the JAMA article. First, the follow-up interval was omitted from the primary composite process outcome due to lack of evidence for any particular follow-up interval and lack of specificity for the reason for follow-up. Subsequent re-analysis including follow-up interval in the process outcome did not materially affect the results (the results are available from the authors).
