TABLE 2.

Five-year cumulative risk of CIN2+ and CIN3+ given HPV35 infection vs all remaining women, among women ages 30 to 64 in the Persistence and Progression (PaP) Cohort at Kaiser Permanente Northern California by ethnicity

Type ethnicity	CIN2+			CIN3+
	5-year cumulative risk		Risk of ethnic group vs other women combined (absolute difference)	5-year cumulative risk		Risk of ethnic group vs other women combined (absolute difference)
	%	95% CI		%	95% CI
HPV35+
White	27.3	22.2-32.5	+4.6	9.7	6.4-12.9	+0.8
Hispanic	21.5	14.3-28.7	−4.3	10.9	5.6-16.2	+2.1
Asian	21.5	12.7-30.3	−4.0	11.0	4.7-17.3	+2.0
African-American	25.1	17.3-32.9	+0.1	5.2	1.5-8.8	−5.0
P-value (Wald-test)	.52			.16

Note: Weight based upon sampling probability of the woman being selected for genotyping (higher for cases vs controls). Risk difference depicts the absolute higher or lower risk of CIN2+ and CIN3+ among women in an ethnic group compared to all other women. P-value = Wald test for heterogeneity.

Abbreviations: CIN2+, cervical intraepithelial neoplasia (CIN) grade 2, CIN grade 3 and cancer; CIN3+, CIN grade 3 and cancer.
