For the article entitled “Study on risk factors and phenotypes of acute exacerbations of chronic obstructive pulmonary disease in Guangzhou, China—design and baseline characteristics” that appears on pages 720-733 (1) of the April 2015 Issue of Journal of Thoracic Disease (JTD), the authors would like to have the following statements added to the Acknowledgements section of the cited article, as follows:
- Evidera holds the copyright for the EXACT and related documents: EXACT© 2013, Evidera, Inc. All rights reserved;
- The EXACT was not designed for prospective use, and the scoring algorithm used by the authors to flag potential exacerbation events was developed independently by the authors, without any interaction with Evidera. Moreover, the alert system developed and applied by the authors differs from the alert systems used in the cited papers (references 13 and 15);
- The study’s alert system to trigger exacerbation events was built on experiences gained from the study by Halpin et al. (reference 14) and extended in such a way that it served the authors’ specific goal of triggering an exacerbation event.
