Upon publication of the original article  it was highlighted by the authors that a grant awarded to support the research work of the study was missed in the Funding Acknowledgements of their manuscript. It should also be acknowledged that the grant titled “Shenzhen healthcare research project” (201505025 to Youde Liang) also contributed to the resources for this research. This has since been formally noted in this correction article.
