169 Available online http://ccforum.com/content/9/2/169 A correction to Pro-atrial natriuretic peptide is a prognostic marker in sepsis, similar to the APACHE II score: an observational study by Nils G Morgenthaler, Joachim Struck, Mirjam Christ-Crain, Andreas Bergmann and Beat Müller. The research article by Dr Morgenthaler and colleagues [1] has an error in the abstract. Currently the abstract reads: ‘On the day of admission, pro-ANP levels, but not levels of other biomarkers, were significantly higher in surviving than in non-surviving sepsis patients’. This should read as follows: ‘On the day of admission, pro-ANP levels, but not levels of other biomarkers, were significantly higher in non-surviving than in surviving sepsis patients’. Reference 1.
