  1. Note: PPV = positive predictive value; NPV = negative predictive value. Results in % with 95% confidence interval (95% CI). CIN1-: The diagnoses of cervical inflammation and CIN1 are referred as CIN1 -; CIN2+: the diagnoses of CIN2, CIN3 and carcinoma are referred as CIN2 +. CIN2-: cervical inflammation, CIN1 and CIN2 are referred as CIN2-. CIN3+: the diagnoses of CIN3 and carcinoma are referred as CIN3 +
