Oral Lesions: Poor Markers of Virologic Failure in HIV-Infected Patients on Antiretroviral Therapy

Table 4

Ability of HIV-related oral lesions to predict a concurrent virologic failure (viral load ≥10,000 copies) at baseline, 6 months, 12 months, 18 months, and 24 months.

Oral lesion	Sensitivity (%)	Specificity (%)	PPV^1 (%)	NPV^2 (%)
Baseline	26.6	90.6	84.1	39.8
6 months	4.5	97.9	45.5	72.8
12 months	5.3	99.6	80.0	78.4
18 months	2.6	98.4	33.3	77.3
24 months	2.8	100.0	100.0	75.4

¹PPV: positive predictive value. ²NPV: negative predictive value.
