Prevalence of HPV35 among HPV-positive women ages 30 to 64 in the Persistence and Progression (PaP) Cohort at Kaiser Permanente Northern California by ethnicity

	n	HPV35+	Weighted percent (95% CI)	Prevalence difference vs other women (95% CI)	P-value
Total	8230	478	5.8 (5.2-6.3)	–
White	4142	237	5.6 (4.8-6.3)	−0.4 (−1.5-0.7)	.3
Hispanic	1775	87	5.1 (4.0-6.2)	−0.9 (−2.2-0.4)	.1
Asian	1609	62	4.0 (3.0-5.1)	−2.2 (−3.4-0.9)	<.01
African-American	704	92	12.1 (9.6-14.6)	+7.0 (4.4-9.5)	<.001

Note: Weight based upon sampling probability of the woman being selected for genotyping (higher for cases vs controls). Prevalence difference depicts the absolute higher or lower HPV35 prevalence among women in an ethnic group compared to all other women. Bold indicates Rao-Scott Chi-square test P-value < .0125, threshold used to account for multiple comparisons. In a test for the pairwise comparison using Poisson regression model, the f-statistic is 18.62 and the global P-value is <.0001.
