Test for heterogeneity between studies: p-value=0.52.

All specimens were HPV52 negative according to consensus primer PCR HPV DNA testing.

^†

Adjusted for age, lifetime number of sexual partners, and study.

^‡

Some specimens from CCCaST study (n=76) were excluded from analysis because number of sexual partners information was not collected from certain subjects (St. John's study site only).
