Table 3 Linkage to care: CD4 and viral load testing done, median CD4 values and median time taken, by study arm

From: A comparison of linkage to HIV care after provider-initiated HIV testing and counselling (PITC) versus voluntary HIV counselling and testing (VCT) for patients with sexually transmitted infections in Cape Town, South Africa

Participants Intervention Control Odds ratio P value
CD4 test done (as % all HIV-positive) 69.9% (n = 228/326) 65.2% (n = 394/604) Adjusted 0.82 (CI: 0.44-1.51) 0.526
    Unadjusted 0.81 (CI: 0.43-1.52) 0.504
Viral load test done (as % of CD4 done) 14.9% (n = 30/202) 10.9% (n = 39/358) Adjusted 0.69 (CI: 0.42-1.12) 0.131
    Unadjusted 0.70 (CI: 0.48-1.02) 0.064
Median CD4 (cells/mm 3 ) (Range) 386 (17–1509) 364 (11–1445)   0.446
Median time (days) from HIV testing to CD4 testing (IQ range) 3 (1–290) 2 (1–337)   0.646
Median time (days) from CD4 to viral load testing for all CD4 categories (IQ range) 245 (177–560) 306 (195–550)   0.622
Median time (days) from CD4 to viral load testing for ART- eligible patients (CD4 ≤ 200 cells/mm 3 )
