Can calculation of energy expenditure based on CO2 measurements replace indirect calorimetry?
OSHIMA, Taku, et al.
Abstract
Background: Methods to calculate energy expenditure (EE) based on CO2 measurements (EEVCO2) have been proposed as a surrogate to indirect calorimetry. This study aimed at evaluating whether EEVCO2 could be considered as an alternative to EE measured by indirect calorimetry. Methods: Indirect calorimetry measurements conducted for clinical purposes on 278 mechanically ventilated ICU patients were retrospectively analyzed.
EEVCO2 was calculated by a converted Weir's equation using CO2 consumption (VCO2) measured by indirect calorimetry and assumed respiratory quotients (RQ): 0.85 (EEVCO2_0.85) and food quotient (FQ; EEVCO2_FQ). Mean calculated EEVCO2 and measured EE were compared by paired t test. Accuracy of EEVCO2 was evaluated according to the clinically relevant standard of 5% accuracy rate to the measured EE, and the more general standard of 10% accuracy rate. The effects of the timing of measurement (before or after the 7th ICU day) and energy provision rates (

During production of article [1], Funding and Competing Interests were published incorrectly due to a publisher error. The errors are detailed below.
Funding
The funding section was included in the original article as below.
The study was funded by the European Society for Intensive Care Medicine (ESICM), the European Society for Clinical Nutrition and Metabolism European (ESPEN), and the public Foundation Nutrition 2000Plus, Switzerland.
This should have been as below instead.
The study was funded by the European Society of Intensive Care Medicine (ESICM), the European Society for Clinical Nutrition and Metabolism European (ESPEN), and the public Foundation Nutrition 2000Plus, Switzerland. The funding bodies were not involved in the study design, the interpretation of the results, or the drafting of the manuscript.
Competing interests
The Competing interests section was included in the original article as below.
TO received financial support as an unrestricted academic research grant from public institutions (Geneva University Hospital) and the Foundation Nutrition 2000 Plus. CP received financial support as research grants and an unrestricted academic research grant, as well as an unrestricted research grant and consulting fees, from Abbott, Baxter, B. Braun, Cosmed, Fresenius-Kabi, Nestle Medical Nutrition, Novartis, Nutricia-Numico, Pfizer, and Solvay, outside the submitted work. The other
authors declare that they have no competing interests related to the current work.
This should have been seen as below.

TO, SG, CH, and CP are currently developing a new indirect calorimeter (The ICALIC study, Clinical Trials.gov ID: NCT02796430). The study is supported by academic societies (see below) and the manufacturer involved (Cosmed, Italy) had no influence on the study conduct and the interpretation of the data in the current work. The other authors declare that they have no conflict of interest related to the current work.
