The analysis was conducted in accordance with the ethical principles of the Declaration of Helsinki and was approved by the appropriate institutional review boards. All sufferers provided written educated consent. The analysis was started in May 2008 and was completed in June 2009. The analysis was designed jointly by the sponsor and the main investigators. The analysis protocol is available with the entire text of this article at NEJM.org. The data were obtained by the study investigators and gathered by Kendle and were analyzed by staff at Rigel and Kendle. The authors had full usage of the data, attest to the completeness and accuracy of the data and analysis, and made a decision to submit the manuscript for publication.Our study has several limitations. As in every scholarly studies that enroll sufferers presenting to emergency departments, recruitment was more difficult on weekends and during out-of-office hours; general, only one third of eligible patients were recruited, although exclusion from the scholarly research by a clinician was rare. The intervention could not be blinded, however the risk of bias was minimized through central randomization to ensure the concealment of study-group assignments and the use of a primary final result that was not at the mercy of observer bias. Because the rate of death was less than anticipated, our study data may not apply to settings with higher mortality. Unlike Rivers et al., within their 2001 study, we did not observe a significant reduction in hospital mortality with the use of EGDT.
