Figure 4. Change in % Ki67, HLA-DR and LPS from baseline.

Change in % Ki67 (a) and % HLA-DR (b) in CD45RA- CD31- cells and in LPS (c) from baseline for children in the substudy. CT  =  continuous ART (antiretroviral therapy), PTI  =  planned treatment interruption (off ART). Changes from baseline were estimated using normal regression of actual measurements adjusting for baseline using the overall mean at randomisation as the reference category.
