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
backgroundTo systematically analyze the epidemiological characteristics and genotype distribution of low-risk human papillomavirus (LR-HPV) infection in Jingzhou, China, and to provide evidence for optimizing regional strategies for the prevention and control of HPV-related diseases.
methodsThis retrospective cross-sectional study included 24,027 women who underwent cervical cancer screening and concurrent HPV genotyping at Jingzhou Hospital Affiliated to Yangtze University between October 2022 and September 2025. A flow-through hybridization technique was employed to detect 27 HPV genotypes (17 high-risk and 10 low-risk types). The prevalence and genotype distribution of LR-HPV were analyzed, with further stratification by age and season.
resultsThe overall HPV infection rate among the 24,027 participants was 25.94% (6,233/24,027), with a LR-HPV infection rate of 10.06% (2,416/24,027). The predominant LR-HPV genotypes were HPV81 (3.33%), HPV61 (2.55%), and HPV44 (1.63%), which differed from the detection rates of the traditionally common LR-HPV types HPV6 (0.82%) and HPV11 (0.32%). The age stratification analysis revealed a U-shaped bimodal distribution of LR-HPV prevalence, with peaks in women aged ≤ 20 years (16.02%) and over 60 years (19.15%) (P < 0.001). Single genotype infections predominated. Seasonally, LR-HPV prevalence was highest in autumn (10.78%) and lowest in summer (9.50%), but the differences were not statistically significant (P > 0.05).
conclusionLR-HPV infection among women in Jingzhou is characterized by a unique regional genotype distribution dominated by HPV81, 61, and 44, with a bimodal age-specific prevalence pattern involving women aged ≤ 20 years and > 60 years. This genotype profile differs from those reported in other regions of China, underscoring the importance of incorporating local epidemiological data into the formulation of regional HPV-related disease prevention and screening strategies.
