Following publication of the original article, the authors flagged the following errors in the author list, affiliations information, and corresponding author information, respectively: (1) the names of the 8th and 9th authors had been inadvertently duplicated (as Xinzhong Chen and Kangjie Xie, respectively); (2) a 6th and a 7th affiliation were erroneously included, and these affiliations were based on information taken from affiliations 4 and 5, with the result that affiliations 4 and 5 were incomplete (in addition to there being a 6th and a 7th affiliation included in error); (3) the correspondence information of the corresponding authors (on the bottom-left of the article PDF) had been ordered the wrong way around, with Xin-Zhong Chen's information being positioned first instead of that of Kang-Jie Xie.

The published article has now been corrected and the corrected information may be seen in this erratum. The authors thank you for reading and apologize for any inconvenience caused.
