The original version of this article contained errors.


In the Design and methods section, under the subheading 'Ethics approval and consent to participate',


"The research is approved by Guangdong Medical University and Middlemore hospital super clinic office. We only use the historical on-line data and X-ray images. There will be no interaction with or impact on patients."


now reads:
