On Mar 22, 2016 the reports for Phase 1 of the South African HIV and TB Investment Case were launched by the Deputy President during the World TB Day celebrations. HE2RO staff were heavily involved in all aspects of the development of the Investment Case, from devising the analytical framework to reviewing evidence for interventions and enablers to developing the novel optimisation method driving the model analysis to writing the reports. The reports are available for download in full (SA HIV_TB Investment Case Full Report Low Res) and summary (SA HIV_TB Investment Case Summary Report Low Res) versions. The Summary report covers the most important aspects of methods, results and conclusions, while the Full report has an important (long) chapter summarising the evidence base for each intervention suggested for inclusion in the IC as well as much more detail on the methods, inputs, and results.
