Dynamic characteristics of high-risk HPV infection in women with low-grade cervical intraepithelial neoplasia, based on a community longitudinal study.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHigh-risk human papillomavirus (HR-HPV) infection is the primary cause of cervical cancer and precancerous lesions. Approximately 35% of women with low-grade cervical intraepithelial neoplasia (CIN1) may experience persistence or progression to high-grade lesions. Yet, the dynamic characteristics of HR-HPV infection in women with CIN1 remain unclear.
methodsA total of 564 women diagnosed with CIN1, recruited from a community-based cohort, underwent a 24-month follow-up at 6th, 12th, and 24th month intervals. Hazard ratios (HRs) with 95% confidence interval (CI) were calculated to evaluate the risk of HR-HPV infection prognosis and their associated factors. Kaplan-Meier survival curves illustrated the dynamic changes of HR-HPV infection and association between HR-HPV infection prognosis and various influencing factors.
resultsHPV16 was the predominant carcinogenic genotype, followed by HPV58 and HPV52. Over the 24-month follow-up, persistent HPV16 infection occurred in 10.6% of women, with 14.4% converting from positive to negative and 4% developing HPV16 positivity from baseline HR-HPV negativity. Rates of persistent infection for HPV58, 52, 18, and 56 decreased over time, with HPV58, 52, and 31 infections more likely to turn HR-HPV negative. Additionally, rates of positive conversion from negative for HPV58, 56, 33, and 66 increased with extended follow-up time. Variables associated with dynamic characteristics of HR-HPV infection prognosis included personal hygiene, age of first menarche, age at first sexual intercourse, educational level, age, and menopausal status (all P < 0.05).
conclusionsThese findings contribute to understanding the dynamic characteristics of HR-HPV infection prognosis in women with CIN1 and its association with non-viral factors.
