On January 21th of 2020, an online meeting was held with the primary investigator and managerial and executive members of the PERSIAN Birth Cohort. In this meeting, all locals presented a brief report on status of the project in their region. The protocols related to data collection were reviewed and some explanations were added. Then members were encouraged to share their ideas to perform novel sub studies from the main project. At last, authorship rules and criteria were reviewed and debated.
