Given the universal use of CD4 and viral load for the assessment of ART effectiveness in clinical trials, our unexpected findings are of concern. Further analyses of independent trials are critically needed to evaluate the utility of prognostic laboratory markers to compare regimens, especially in resource-limited settings with high background
Navitoclax clinical trial morbidity and where, following the public health approach to ART provision [2] and given limited formularies, first-line ART is often continued to clinical rather than immunological or virological failure. We thank all the participants and staff from all the centres participating in the NORA and DART trial. MRC/UVRI Uganda Research Unit on AIDS, Entebbe, Uganda: H. Grosskurth, P. Munderi, G. Kabuye, D.
