Compliance with ethical standards
:
: The authors declare that they have no conflict of interest.
: This project was supported and approved by Tianjin Municipal Health and Family Planning Commission on August, 2015. However, the Ethics Committee in our hospital (Tianjin Nankai Hospital) was not officially established until 2017. For projects approved before 2017, the procedures of ethical examinations were incorporated into the review processes. Therefore, all the approved projects before the establishment of the Ethics Committee have passed de facto ethical examinations in order to receive financial support.
