1
kappa coefficient of concordance; 95%CI- 95% confidence intervals; NE- could not be evaluated. Strength of agreement is poor when of value of kappa is <0.000; slight when kappa among 0.000–0.200; fair when 0.210–0.400; moderate when 0.410–0.600; substantial when 0.610–0.800. Moderate or substantial agreements are in bold.
2
precision is percentage of agreement (number DNA negative or positive for the same type specific β-HPV in any two paired samples)/(total number of any two paired samples).
