Human Papillomavirus 16 Lineage A Variants Associated With Persistent Genital Infections in Men: The HPV Infection in Men (HIM) Study.
Article in The Journal of infectious diseases, 2023. 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) 16 non-A lineage variants have higher carcinogenic potential for cervical cancer. HPV-16 variants natural history among males is not established. We evaluated HPV-16 variants prevalence and persistence in the external genitalia of men enrolled in the prospective HPV Infection in Men (HIM) Study.
methodsThe HIM Study included men from the United States, Brazil, and Mexico. HPV-16 variants were distinguished using polymerase chain reaction sequencing. The prevalence of HPV-16 variants was assessed, and associations with infection persistence were estimated.
resultsWe characterized the HPV-16 variants for 1700 genital swab samples from 753 men and 22 external genital lesions in 17 men. The prevalence of HPV-16 lineages differed by country and marital status (P < .001). Overall, 90.9% of participants harbored lineage A variants. The prevalence of non-A lineages was heterogenous among countries. HPV-16 lineage A variants were associated with a 2.69-fold increased risk of long-term persistent infections compared with non-A lineages. All high-grade penile intraepithelial neoplasia harbored lineage A variants and occurred in the context of long-term persistent infections with the same variants.
conclusionsThe prevalence and persistence of HPV-16 variants observed at the male external genitalia suggest differences in the natural history of these variants between men and women, which may be associated with intrinsic differences in the infected genital epithelia.
