7. "The impact of anesthesiologists on coronary artery bypass graft surgery outcomes" (Glance 2015)
Retraction
As explained by Glance and Dick, the findings of the 2015 article “The Impact of Anesthesiologists on Coronary Artery Bypass Graft Surgery Outcomes” are incorrect because of flawed statistical analysis. The article is therefore retracted. The data in the retracted article are a subset of a revised analysis appearing in this issue of Anesthesia & Analgesia. The authors’ diligence in identifying the error and correcting the analysis is acknowledged with appreciation.
