Correction to: Obesity Surgery

In the original article some of the references were ordered incorrectly.

The correct reference 34 is: Hardman JG, Aitkenhead AR. Estimating alveolar dead space from the arterial to end-tidal CO(2) gradient: a modeling analysis. Anesth Analg. 2003;97(6):1846–51.

From reference 35 forward, all references are increased by one number and appear as below:
