Research

National systems, used in published research.

EDRWeb and TIER.Net do operational work first. The records they hold have also supported independent research into tuberculosis, HIV care, treatment outcomes, programme monitoring and data quality.

This is a selected reading list, not a claim of authorship. WAMTech built and has supported these systems; the studies and their conclusions belong to the named researchers and publishers.
