Patients initiating treatment became slightly healthier over time, with decreasing TB (25.1% in 2004, 8.2% in 2013), higher initiating CD4 counts (22.4% <50 cells/mm3 in 2004, 12.4% in 2013) and fewer underweight patients in later years (12.2% in 2004, 7.7% in 2013). This evidence concerns the gene CD4 and tuberculosis.
