Natural history of HPV-16 E6 serology among cancer-free men in a multicenter longitudinal cohort study.
Article in Journal of the National Cancer Institute, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHuman papillomavirus (HPV) type 16 E6 protein seropositivity accurately predicts oropharyngeal squamous cell carcinoma risk decades before diagnosis; but the biomarker's translational potential is unknown. To inform considerations for oropharyngeal squamous cell carcinoma screening, we described HPV-16 E6 seroprevalence, predictors, and kinetics among cancer-free men.
methodsIn a cohort study in Brazil, Mexico, and the United States, we calculated HPV-16 E6 seropositivity (median fluorescence intensity > 1000), measured by multiplex serology, in cancer-free men. We assessed HPV-16 E6 seropositivity predictors using logistic regression, adjusting for country, age, sexual orientation, and lifetime number of sexual partners. Among HPV-16 E6 seropositive men, we retrieved all available retrospective serum samples and described temporal HPV-16 E6 antibody patterns.
resultsOf 3997 men, 14 had HPV-16 E6 antibodies detected (seroprevalence = 0.35%, 95% CI = 0.19% to 0.59%; median fluorescence intensity = 2407 [IQR = 1325-5986]). Older age was associated with increased odds of HPV-16 E6 seropositivity (50-84 years vs 18-29 years odds ratio = 16.61, 95% CI = 2.20 to 417.03). Serum from 11 of the 14 seropositive men retested positive; 6 men had median fluorescence intensity above 5000, of whom 2 had median fluorescence intensity greater than 10 000. Seven men had 3 or more years of follow-up; all were persistently seropositive for 3 years. One man was seropositive for 9 years but seroreverted at his exit visit. Oral HPV-16 DNA (prevalence = 1.13%) was associated with HPV-16 E6 seropositivity (odds ratio = 16.87, 95% CI = 3.35 to 69.55), but oral HPV-16 DNA positivity was not persistent over follow-up, even when HPV-16 E6 antibodies were persistently detected.
conclusionAlthough HPV-16 E6 seropositivity is rare, it is generally stable once detected; thus, HPV-16 E6 antibodies may be an informative biomarker of HPV-driven oropharyngeal squamous cell carcinoma. Few men seroreverted following HPV-16 E6 seropositivity but remained close to the seropositivity cutoff; thus, cancer risk among these men is less clear.
