Table 4 Accuracy of HPV and VIA to predict p16 INK4a/Ki-67 dual stain positive infections. PPV = positive predictive value, NPV = negative predictive value

From: Novel concepts in cervical cancer screening: a comparison of VIA, HPV DNA test and p16INK4a/Ki-67 dual stain cytology in Western Kenya

Test Sensitivity, % (95% CI) Specificity, % (95% CI) PPV, % (95% CI) NPV, % (95% CI)
HPV 94 (70–100) 69 (65–72) 7 (6–8) 99 (99–100)
VIA 13 (2–40) 93 (91–95) 4 (1–14) 98 (97–98)
VIA triage of HPV positives 13 (1–40) 93 (89–96) 12 (3–36) 93 (92–95)
