Erratum

In the original publication of this article [1], published on 8 March 2017, figure 2 and 3 contained a wrong figure caption. The original captions are as followed:

  • Figure 2 Flow chart of the study participants. Ref: Ministry of Public Health. Summary of Thailand Health Tourism. Nonthaburi: 2014

  • Figure 3 Diseases treated in the previous 12 months. Ref: Ministry of Public Health. Summary of Thailand Health Tourism. Nonthaburi: 2014

However, these figures are not taken from the reference Nonthaburi 2014, and the captions should have read:

  • Figure 2 Flow chart of the study participants.

  • Figure 3 Diseases treated in the previous 12 months.

The original publication of this article has been corrected. The publisher apologizes to the readers for the inconvenience caused by this typesetting error.
