The authors regret there is an error in the reported study enrollment period and an inclusion criterion in the above paper. The reported study period is between January 2000 and February 2008. A recent reabstraction of the data demonstrated that the end date of the enrollment period was actually September 2009. Additionally, the Results section reports that the analysis was conducted on 9280 index cardiac arrest events; the set of 9280 events includes non-index events as well prior to their exclusion.
