  1. Note: the initial and district database are equivalent for the KZN province. Therefore completeness was counted in both columns for KZN if there was a value recorded for the given variable in the initial ETR database
  2. *Chi-squared comparison of proportions across all columns
  3. aInformation on HIV status is not available at a patient level at higher levels of administration for reasons of confidentiality. Completeness of the data for HIV status at these levels of the ETR was therefore not able to be determined
