Genotype distribution and molecular characterization of HPV in the Peruvian amazon: insights into prevalence, lineage diversity, and viral integration.
Article in Scientific reports, 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
Cervical cancer remains a leading cause of cancer-related mortality among women in Peru, with the highest death rates reported in the Amazon region. Despite this burden, molecular data on human papillomavirus (HPV) in this area are limited. This study aimed to assess HPV genotype distribution and molecular characteristics in women undergoing cervical screening in the Peruvian Amazon. Between May and November 2024, cervical samples were collected from 503 women aged 25-55, along with an additional subset of 35 women with histologically confirmed CIN2 + lesions. HPV genotyping was performed using the Allplex™ HPV28 assay, and single infections with HPV16 or HPV52 were further analyzed by TaME-seq to determine lineage, intrahost variability, and integration. HPV prevalence was 51.7% (278/538), with high rates of multiple infections (44.2%) and low vaccination coverage (7.8%). Oncogenic HPV types were detected in 35.7% (192/538) of participants, with HPV 16 and HPV 52 being the most prevalent. Sublineage analysis revealed predominance of A1 variants, while viral integration was detected in nine cases, three associated with CIN2 + lesions. Integration sites occurred mainly in E1/E2 for HPV16 and L1/L2 for HPV52. These findings highlight the urgent need to expand vaccination and implement molecular screening strategies in the Peruvian Amazon.
