Correction to: Archives of Public Health 78, 75 (2020)
Following publication of the original article [1], the authors reported an error of the ethical code in the Ethics approval and consent to participate section.
The original version was:
While each cohort center received the ethical approval from local universities, for the purpose of this study and pooling all PERSIAN data, the ethics committee of Kermanshah University of Medical Sciences approved the study (IR.KUMS.REC.1397.187).
The correct version is:
While each cohort center received the ethical approval from local universities, for the purpose of this study and pooling all PERSIAN data, the ethics committee of Kermanshah University of Medical Sciences approved the study (IR.KUMS.REC.1397.866).
The original article [1] has been corrected.
