Interferon-γ–Inducible Protein 10 Classification Performance for Predicting Viremia Compared to Gold Standard Viral Load

VL Result (Gold Standard)
IP-10 Classification	Undetectable VL	Detectable VL	Total
No case	125 (59.5)	11 (10.4)	136 (43.0)
Potential VF	85 (40.5)	95 (89.6)	180 (57.0)
Total	210 (100)	106 (100)	316 (100)

Data are presented as No. (%). IP-10 model with a cutoff of ≥44.2 pg/mL was compared to gold standard VL for classification performance of individuals with detectable VL (>150 copies/mL). Note that both training and validation sets were included to simulate a hypothetical classification in a cross-sectional cohort in Mozambique.

Abbreviations: IP-10, interferon-γ–inducible protein 10; VF, virologic failure; VL, viral load.
