the claim

The prevalence of HPV-16, -18, and/or -31 DNA in cervical lesions increases with the severity of the lesions.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the prevalence of HPV-16, -18, and/or -31 DNA in cervical lesions increases with the severity of the lesions?

Yes. Multiple studies demonstrate that the prevalence and viral load of high-risk human papillomavirus genotypes, particularly HPV-16, increase progressively with the severity of cervical and vaginal lesions.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved literature consistently supports the claim that high-risk HPV types such as HPV-16 and HPV-18 (as well as others like -31) increase in prevalence, detection rate, and viral load as the histopathological severity of cervical and vaginal lesions increases from low-grade to high-grade intraepithelial neoplasia and cancer.
