Figure 2From: Mean CD4 cell count changes in patients failing a first-line antiretroviral therapy in resource-limited settings a: Mean CD4 cell count change between M6-M12 relative to the M6 viral load (adjusted, threshold = 10,000 copies/ml). b: Mean CD4 cell count change between M12-M18 relative to the M12 viral load (adjusted, threshold = 10,000 copies/ml). c: Mean CD4 cell count change between M6-M12 relative to the M6 viral load (adjusted, threshold = 5,000 copies/ml). d: Mean CD4 cell count change between M12-M18 relative to the M12 viral load (adjusted, threshold = 5,000 copies/ml).Back to article page
