Incidence, persistence, and clearance of cervical human papillomavirus infection among gynecological outpatients in Kunming, Yunnan, China, 2019-2023: a retrospective cohort study.
Article in PeerJ, 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
Human papillomavirus (HPV), a leading sexually transmitted pathogen, is characterized by persistent infection, which represents a critical risk factor for cervical carcinogenesis. This retrospective cohort study investigated the epidemiology of HPV among 45,149 gynecological outpatients in Yunnan, China (2019-2023). The 12-month cumulative incidence of HPV infection was 36.84%, with the highest rates observed in the 30-49-year age group. HPV-52 was the predominant subtype, followed by HPV-51, -81, -58, and -16. Persistent infection was observed in 55.56% of cases, most frequently involving HPV-42, -52, -58, -81, and -56, with higher rates in individuals younger than 30 and older than 59 years. Overall clearance reached 74.43% and was inversely correlated with age. Rapid clearance was predominantly observed for HPV-26, -83, -11, -82, and -44, whereas high-risk HPV types (HPV-58, HPV-52, HPV-35) and low-risk types (HPV-42, HPV-81, HPV-43) exhibited prolonged persistence. Regional data indicate elevated risks of incident and persistent infections with HPV-58, HPV-52, HPV-42, and HPV-81, with older populations showing greater susceptibility to persistence and younger individuals demonstrating faster clearance. These findings underscore the age-specific dynamics of HPV infection and highlight priority subtypes for regional cervical cancer prevention strategies.
