The data sharing statement is incorrect. The correct statement is:

The data are bound by ethical and legal restrictions. To access the data of the South Africa's Prevention of Mother to Child Transmission Effective study, investigators that are not part of the study team should submit a concept proposal to Thu-Ha Dinh, MD, MS (US Centers for Disease Control and Prevention (CDC), Principal investigator), Ameena Goga, MD, MS (South Africa Medical Research Council (MRC), Principal Investigator) and Debra Jackson (University of the Western Cape/UNICEF, Principal Investigator) for approval. Investigators with an approved concept proposal must apply for guest researcher status obtain access to a workstation and the data. Additionally they will need to complete data security and confidentiality training, and to sign data use and nondisclosure agreements.
