Gaps in linkage to care: proportion of HIV-positive patients with no record of CD4 testing and the proportion of ART-eligible patients with no record of viral load testing, by study arm. Figure 1 shows the main outcomes as a cascade of care to illustrate the gaps in linkage to care after testing HIV-positive in both arms of the study. The first gap in linkage to care was those HIV-positive patients who did not have a record of CD4 testing (indicated by the top set of brackets). The proportion of those patients with CD4 test records is represented by the second set of maroon-coloured bars. The third set of smaller green bars is the proportion of those with CD4 records who were ART-eligible. The last set of small, purple bars indicate those ART-eligible patients with records of viral load tests (expressed as a proportion of those who were ART-eligible). Finally, the second gap in linkage to care in the graph is the proportion of ART-eligible patients with no record of viral load testing (shown by the lower set of brackets).
