Erratum to: The Preventive Effects of Posterior Pericardiotomy with Intrapericardial Tube on the Development of Pericardial Effusion, Atrial Fibrillation, and Acute Kidney Injury after Coronary Artery Surgery: A Prospective, Randomized, Controlled Trial

It has been brought to the Editor's attention that Table 2 in the above publication contains an error in measurement units. The amount of pericardial effusion by echocardiography is measured in mm, not in mL. Article published efirst on April 14, 2015. DOI of the original article: 10.1055/s-0035-1548737.

After consultation with the authors the corrected and re-arranged table now looks like follows :
