Comparison of S-WET and S-DRY in identifying various HPV genotypes

HPV detected	Number of samples				Positive agreement*
	WET+ DRY+	WET+ DRY-	WET- DRY+	WET- DRY-
Subject level comparison
Any HPV	61	16	0	35	88.4%
HPV 16 and/or HPV 18	32	13	2	65	81.0%
Other HR-HPV	47	12	1	52	87.9%

Note: HPV prevalence analyzed on subject level: subjects infected with HR-HPV/ specific HR-HPV types compared with those not infected with HR-HPV/ specific HR-HPV types.

*The observed proportion positive agreement=2a/(N+(a2d)), where a=the number of samples that were positive for HPV in both the wet and dry samples, d=the number of samples that were negative for HPV in both the wet and dry samples and N=all samples tested for HPV.

S-DRY dry vaginal swabs used for self-sampling, S-WET vaginal swabs with wet transport medium used for self-sampling.
